                   INTRODUCTION
       Recent  public  concern  about  the health
  effects from  exposure  to  radon   has greatly
  increased the demand for companies qualified to
  measure  radon  and  radon  decay  products  in
  indoor air.    In  response  to states'  requests
  for   assistance,    the   U.S.    Environmental
  Protection   Agency's   Office   of   Radiation
  Programs  has  developed   the  National   Radon
  Measurement   Proficiency  (RMP)   Program  within
  its Radon  Division.     Under  this program,  any
  company   offering   measurement   services   is
  invited to   demonstrate   its  proficiency   in
  measuring   indoor  radon  gas  and  radon  decay
  product concentrations.
       The program's _ Immediate  nblectlve   |s  trj
  assist  States and the  publin  In ejecting onm-
  Panies   that  have remonstrated  competent  in
          g - indoor _ radon   and   radnn
 Products.  This   is  achieved by evaluating, on
 an  EPA  scheduled  basis,  the  proficiency of
 companies'  measurements  and  the  quality  of
 their  data  management.    The  companies that
 demonstrate their  proficiency  in  each of the
 areas are listed in this Cumulative Proficiency
 Report.   The  program's  long-term objectives are
 to  promote   standard   measurement  procedures
 among  measurement  companies   and   to establish
 quality     assurance     procedures     for    all
 measurement companies.
     The  National  RMP  Program   Is  not d
     accrediting  measurement  companies.   Nnr
        Li - certify.   recommend.   or  endnrsg
participating companies.    The  inclusion of a
company   in   this   report   should   not  be
interpreted as a certification or accreditation
of that company.  This  report is only a source
  of measurement companies that have demonstrated
  capabilities  for  measuring  radon  and  radon
  decay products.
       The testing  periods  are  referred  to as
  test  "rounds".      A   company   enrolls  its
  measurement method(s) (e.g., activated charcoal
  adsorption) for evaluation.   A primary company
  either owns analysis  capabilities or makes all
  measurements   and   analyses   with    its  own
  instrumentation and  operators.     This type of
  company   may  or    may  not  offer measurement
  services directly to  the   public. A secondary
  company  offers  services  ranging  from  detector
  distribution    to    home     inspection     and
  consultation.   It must  use  one of the primary
  companies for  its detector  analyses.
      The EPA instructs the  primary companies to
  submit a specific number  and type of detectors
  (e.g., five  charcoal  canisters) for exposure to
  known  levels of radon  and radon decay products.
  After exposure  in  a   federal radon chamber, EPA
  returns the  detectors  to  the company without
  revealing the radon gas  or radon decay product
 concentration.      The   company  analyzes  the
 detector(s)   and  reports  its  measurements to
 EPA.   The EPA  compares these measurements with
 the known levels of exposure.   If the  company's
 results are   within  the  estabIished screening-
 measurement     criterion,     it     passes    the
 performance  test with  that method.
     Companies   meeting     all   the    program
 requirements  for a  given  method are  listed  in
 this   Cumulative   Proficiency   Report.     A
 company's method that  fails  after  having been
 listed  in a previous  round's report is omitted
entirely  from  this  report  and  will  not be
reinstated    until     its    next   successful

-------
 performance in a round.
      Table 1  lists all  the proficient companies
 for   the  methods  shown  serving  each  State.
 Numerous companies distribute mail-in detectors
 and    make   measurements   nationwide.     The
 companies offering nationwide service are under
 the   "Nationwide"  heading,    and  precede  the
 individual  State headings.
      Table 2   lists  the companies'  performance
 indicators   for   each    round    up   to  four
 performance rounds.   In   a  case  where a company
 offers primary  services  for   one method but not
 another,  the  performance  indicators in Table  2
 are  underscored to mark  the  method(s) for which
 it  is  a  primary  company.     In  addition,  it
 indicates if  they  are  "primary" or  "secondary"
 companies,    and   shows   whether   they  have
 submitted  acceptable  quality  assurance  (QA)
 plans.    The   EPA  has   requested,  but has not
 required,  that   participating companies submit
 for  review a  copy  of  their   QA plans.   A "Q1"
 indicator  instead  of   an   "L1"    in  Table  2
 indicates that  the company  has submitted a plan
 that  complies with the  QA criteria recommended
 by this program.

        SELECTION OF MEASUREMENT  METHOD
      Several different   measurement  methods may
 be used to  determine  the  radon or  radon decay
 product  concentrations  in houses.   In  practice,
 the choice  of a  method  is often  dictated  simply
 by avallability   ~   if  an   adequate  method is
 available,  you use  it.    If alternative methods
 are available, then the cost  or  the duration of
 the measurement may become the deciding factor.
     The    EPA    has   developed   measurement
protocols   for  eight   different  methods  and
 believes   that   any   of    them,   when  used  in
 accordance  with  EPA  protocols,   can   produce
 valid  results.    This  does   not   mean  that all
-measurements made according   to   the suggested
 protocols  wi 1 1   produce   results  with identical
 certainties.  However,   it  does   mean  that the
 listed  methods    are   capable    of  producing
 adequate   results for   screening   or  followup
 purposes.
     Each  method  has  its  own   advantages and
 disadvantages.   Users must decide  which method
 is best suited to their  situations.   The  fol-
 lowing sections   detail   the  characteristics of
 the eight  methods,   pointing out  some of  the
 advantages and disadvantages  of each  one.   This
 summary is not   exhaustive,   but  is intended to
 guide the  user  in making  an informed  selection
 of a measurement method.
Continuous Radon Monitoring  (CR) and
 Continuous Working-Level Monitorin
     These  measurement   methods  are  similar
because they both use an electronic detector to
accumulate and store  information related to the
periodic      (usually      hourly)     average
concentrations  of  radon  gas  or  radon decay
products (working level).  They are deployed in
houses  according  to  guidelines  in  the  EPA
protocol, and  then  turned  on,  or programmed
for, the desired operating time — a minimum of
six hours for  screening  and twenty-four hours
for followup measurements.    At  the end of the
test,  the monitor  must  be  retrieved,  and the
results  must   be   analyzed   by   a  skilled
instrument  operator.
     Advantages
     •   Relatively short  measurement  duration.

-------
      •   Hourly  results  can  track  the  variation
         of  concentrations  in  the  house.
      •   Very  precise  (most  models).
      •   Results  are available on-site (for  CW).

      Disadvantages
      •   Relatively  expensive,  cost   may range
         from  $100 to  $300,  depending  on the
         type  of  services provided.
      •   Requires a skilled  instrument  operator.
      •   This, as  does  any short-term measure-
         ment,  requires   careful   control  of
         closed-house  conditions twelve hours
         before and during the  test.
      •   Because of  the  highly reactive nature
         of radon decay products, the  continuous
         work ing-1 eve I   measurements   are  much
         more  susceptible to sampling  error than
         radon gas measurements.
Aloha-Track Detection (AT1)
     The  alpha-track  method  measures  radon.
The  detector   is  a  small  sheet  of  special
plastic material enclosed  in a container with a
filter-covered opening.    The  radon  gas that
enters  the  container  decays,  emitting alpha
particles.   The  particles  strike the plastic
sheet, leaving  tracks  that  can be chemically
enhanced and counted  using  a microscope or an
automated counting system.
     The detectors  are  deployed  in  the home
according to  guidelines   in  the EPA protocol.
They are left for periods of up to three months
for screening  and  twelvp  months for followup
measurements.  At the  end of the desired test-
ing period,  they must  be  returned to the dis-
tributor  or  analytical   laboratory for process-
ing and evaluation.
      Advantages
      •   Relatively low-cost  services;  cost may
         range  from $20 to  $60.
      •   No  special  skills  required for making
         the measurement.
      •   Can be distributed by  maiI.
      •   Completely passive,  needs  no external
         power.
      •   Can measure the   long-term average con-
         centrations over a twelve-month period,
         which  is the optimal measurement  of
         long-term  concentrations.
     Disadvantages
     •  Relatively    long   measurement  period
        necessary; three  months   is the recom-
        mended minimum for currently available
        detectors.
Activated Charcoal Adsorption (CO
     The  charcoal  adsorption  method measures
radon  gas.    The  detectors  for  this method
consist  of   variously  configured  containers
filled  with  a  measured  amount  of activated
charcoal.  The  container  is usually perforated
or screened to  keep  the charcoal from falling
out, and some have  a  filter to keep out radon
decay products.    All  charcoal  adsorbers are
stored in  airtight  containers  when not being
used for sampling.
     Charcoal adsorbers can be received through
the mail  from a distributor.  They are deployed
in the home for  up  to seven days according to
guidelines in the EPA protocols.  At the end of
testing,  an adsorber  is  resealed and returned
to the distributor or analytical laboratory for
processing and evaluation.

     Advantages
     •   Low  cost  for  services;  costs  may  range
        from  $10  to  $25.

-------
         Can be distributed  by mail.
         No special skills needed for making the
         measurement.
         Completely passive, needs no external
         power.
         With proper analysis, can yield precise
         results.
      Disadvantage^
      •  Some charcoal adsorbers are more sens!
         tive than others to temperature and
         humidity.
      •  Limited to short-term testing.
      •  Requires, as does  any short-term meas-
         urement ,  careful   control   of closed-
         house conditions twelve hours before
         and during the test.
 RPISU  -  Radon  Progeny  integrating  Samn||nn
 Unit
     The  RPISU  method  measures   radon  decay
products.  RPISU detectors have a flow-rate air
pump  that  pulls  air  continuously  through a
detector assembly.  Depending on the model, the
unit  can   be   installed   and    operated  by
homeowners or skilled  operators for three days
or longer, according  to  guidelines in the EPA
protocol.    At  the  end  of  that  time,  the
homeowner sends it  to  the  distributor, or an
operator removes the unit and returns it to the
analysis   laboratory    for   processing   and
evaluation.

     Advantages
     •   Directly measures concentrations of
        radon  decay products.
     •   Relatively  short  measurement period.
     •   The detector  assembly  and  some entire
        units  can be  sent by mai I.
     •   There  is  extensive  experience   in  the
        use of  RPISU's; therefore, measurement
        errors  are  well established.
       Disadvantages
       •   Relatively   expensive;   cost   may  range
          from  $40  to  $150,  depending on type  of
          service provided.
       •   Some  models  may  be both  heavy  and
          awkward to move.
       •   May be  limited to  locations with AC
          power.
       •   Some  units must  be installed and picked
          up by a skilled  instrument operator.
       •   Because of  the  highly  reactive nature
          of radon  decay  products, measurements
          are much more susceptible to sampling
          error than radon gas measurements.
 Grab Radnn fGRl and Rrah Worklng-lPvff| ffjW)
      The grab sampling  methods measure concen-
 trations of  radon  gas  or  radon decay product
 concentrations (working-level).   The radon grab
 sample is collected in  a special  flask holding
 100  to 2,000  cubic  centimeters  of  air.   The
 radon  decay  product grab sample  is  collected by
 drawing air  through  a  filter upon which  radon
 decay  products,   if  present   in  the   air,  are
 collected.     Both    samples  can   be   acquired
 simultaneously  with some detector systems.   All
 sampling   should  be   done   in   accordance with
 guidelines in the EPA  protocols.
     For  results of  the  grab radon  test, opera-
 tors must  return  to   their  offices to analyze
 the exposed detectors, and must  delay the anal-
ysis for at  least four hours after  the testing.
For  most   grab   working-level   (radon  decay
products)  tests,   operators  can  perform  the
analysis on location in an hour or  less.

     Advantages
     •   Results are  quickly obtained.
     •   Equipment  can be  portable.

-------
       •  Some detector systems can sample both
          radon gas and radon decay products
          simultaneously.
       •  Can acquire and  evaluate several
          samples per day.
       •  Conditions during the measurement are
          known to the operator.
       Disadvantage^
       •   Relatively  expensive;  costs  may  range
          from $80  to $300,  depending  on the  type
          of services offered.
       •   Very short  measurement periods may  not
          be representative  of the  long-term
          average concentrations.
       •   Requires  a  skilled operator.
       •   Requires, as does  any short-term meas-
          urement,  careful  control  of  closed-
          house conditions twelve hours before
         and during the test.
      •  Because of  the  highly reactive nature
         of  radpn  decay  products,  grab radon
         decay  product  measurements  are  much
         more  susceptible to sampling error than
         radon gas measurements.
  Advantages
 E-PERM
      E-PERM   (Electret    Passive   Environmental
 Radon  Monitor)  is   an  Integrating  detector  used
 to  measure   radon   gas.     It   Is  a   canister
 containing a  charged  electret  which  reacts to
 the  radiation  emitted   from  radon   and radon
 decay  products.
     E-PERMs  can be  received  through  the  ma i I
 and installed  in a home according  to guidelines
 in the EPA protocol  for  two  to  seven days or
 three  to  twelve   months,  respectively,  for
 short or long-term E-PERMs.   At the end of the
 testing period, it is  resealed and returned to
 the analytical  laboratory  for  processing and
evaluation.
       •  The E-PERM is  a relatively inexpensive
          (cost may range  from  $8  - $25) small
          detector that produces a result that is
          a true integrated average radon concen
          tration.  *
       •  Two  types  of  'E-PERMs  are avaiI able,
          allowing the method to be used for  both
          short-term and  long-term measurements.
       •  The laboratory   analysis  of  E-PERMs is
          nondestructive,  allowing results  to be
          verified if  necessary.
 Disadvantages
      •  E-PERMs  are  sensitive  to  background
         gamma   radiation,    necessitating   a
         background check and subtraction of an
         increment of voltage.
      •  EPA does not have extensive experience
         with this method.
             PROGRAM REQUIREMENTS
      For  each  method,   participants  must send
 with their  applications a copy of  the operating
 instructions  they   provide  homeowners   and/or
 those used  by  an   instrument  operator.   These
 instructions  must    reflect    the   measurement
 procedures  found  in  the EPA documents, "Interim
 Indoor Radon and  Radon  Decay  Product Measure-
 ment  Protocols"  and   "Interim  Protocols  for
 Screening and   Followup  Radon   and  Radon Decay
 Product Measurements".    They  must  be accepted
 by, and  on   file  with,  EPA  by  the deadline
 specified on  that round's schedule.
     Once enrolled,  a   company   must meet EPA's
 minimum screening-measurement  requirements for
 each method.  A  company must meet all detector
and analysis result  deadlines  as listed on the
program schedule.   Applications, detectors, and

-------
analyses   reporting   forms   received   after
scheduled deadlines wl11   not  be considered in
the performance  evaluation  process.    A com-
pany's detector(s) must  be successfully tested
every round to maintain its proficiency
listing.
