INTRODUCTION
Recent public concern over the health
effects from exposure to radon has greatly
increased the demand for companies qualified to
measure radon and radon progeny In Indoor air.
In response to States' requests for assistance,
the U.S. Environmental Protection Agency's
Office of Radiation Programs has developed the
Radon/Radon Progeny Measurement Proficiency
(RMP) Program. Under this program, any company
offering measurement services directly, or
Indirectly through another company -- Is Invit-
ed to demonstrate its proficiency in measuring
radon gas and radon progeny levels.
The program's Immediate oblectlve Is to
assist States and the public In selecting com-
panies that have demonstrated competence in
measuring Indoor radon and radon orogeny. This
is achieved by evaluating, on a semiannual
basis, the proficiency of companies' detector
operations and the quality of their data man-
agement. The companies that demonstrate their
proficiency are listed In the RMP proficiency
reports. The program's long-term objectives
are to promote standard measurement procedures
among measurement companies and to establish
quality assurance procedures for all measure-
ment companies.
ThP RMP Program Is nnt designed for ac-
crediting measurement companies.HOT JOS? It
certify, recommend, nr endnrse participating
companies. The Inclusion of a company In this
report should not be interpreted as a certifi-
cation or accreditation of that company. This
report is only a source of measurement compa-
nies that have demonstrated capabilities for
measuring radon and radon progeny levels.
The testing periods are referred to as
test "rounds". Each round consists of two
tests <- a performance test and a follow-up
test. A company enrolls Its measurement
method(s) (e.g., activated charcoal adsorption)
for evaluation. EPA tells the company to sub-
mit a specific number and type of detectors
(e.g., five charcoal canisters) for exposure to
known levels of radon and radon progeny. After
exposure in a federal radon chamber, EPA re-
turns the detectors to the company without
revealing the radon gas or .radon progeny lev-
els. The company analyzes the detector(s) and
reports its measurement results to EPA. EPA
compares the measurement results with the known
levels of exposure. If a company falls any. of
the program requirements in the performance
test, It must retest in the follow-up test.
The same detector submittal and exposure proce-
dures are followed for the follow-up test.
Companies that fail this second attempt may
participate in the next test round.
Only companies having met all the program
requirements for a method In either the per-
formance or the follow-up test are listed in
this Cumulative Proficiency Report. The com-
panies that meet all the program requirements
in the initial performance test are listed with"
an "LI" Indicator under the appropriate meth-
od(s). Companies that meet all the require-
ments In the follow-up test are listed with an
"LA" indicator under the appropriate method(s).
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 rein-
stated until Its next successful performance In
a round. When the method passes again, its
performance Indicators for the previous three
-------
rounds as well as for the present round will be
listed. Upon reinstatement, the round during'
which the method had failed will be narked with
an "NL" Indicator, signifying its omission from
that round's report.
Table 1 lists all the proficient companies
serving each State. Numerous companies distri-
bute mall-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 over a two-year peri-
od. In addition, it Indicates If they are
"prlaary" or "secondary" companies, and shows
whether they have submitted acceptable quality
assurance (QA) plans.
A prlaary company either owns analysis
capabilities or makes all measurements and
analyses with Its own Instrumentation and oper-
ators. This type of company may or may not
offer aeasurement services directly to the
public. A secondary company's services may
range froa detector distribution to home In-
spection and consultation. This type of com-
pany aust use one of the primary companies for
its analyses. In a case where a company offers
primary services for one method but not anoth-
er, the perfornance indicators In Table 2 are
underscored to mark the method(s) for which It
Is a prlaary company. EPA has asked, but has
not required, that participating companies
subs It for review a copy of their QA plans. An
X under the column headed "QA Plan" in Table 2
Indicates that the company has submitted a plan
that compiles 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 progeny
concentrations In houses. In practice, the
choice of a method Is often dictated simply by
availability 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.
EPA has developed measurement protocols
for seven 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 ac-
cording to the suggested protocols will produce
results with Identical certainties. However,
it does mean that the listed methods are capa-
ble of producing adequate results for screening
or follow-up 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 seven 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 Monitoring (CW) -
These measurement methods are similar in
"; ,;rt ) fr/p^jvy
that they use an electronic detector to accumu-
late and store information related to the perl-
' : ' .si.j X'ift* v,i jnsftfisnaq JsrtJ
odlc (usually hourly) average concentrations of

-------
guidelines fn 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 follow-up measure-
ments." "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 nay range
froi $100 to $300, depending on the
type of services provided.
Requires a skilled Instrument operator.
this, as does any short-term measure-
aent, requires careful control of
,;.. closed-house conditions twelve hours
before and during the test.
Because of the highly reactive nature
of radon progeny, the continuous
,,^working-1eve I measurements are much
more susceptible to sampling error than
radon gas measurements.
Aloha-Track Detection (AT)
The alpha-track method measures radon. An
AT detector Is a small sheet of special plastic
material enclosed in a filtered container. The
container collects the radon progeny on the
filter paper while the radon gas enters the
container. As the gas and some of the short-
lived progeny decay, they emit alpha particles
< '.. /,: oj ': ..! . ' '
that permanently mark the plastic sheet.-,.
Jo gfioIj-siJnsonoo sgeisv? (v; ;..,;,.
The detectors are Installed in the home
according to guidelines In the EPA protocol.
They are left for periods of up to three months
for screening and twelve months for follow-up
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-
centratlons 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 often perforated or
screened to keep the charcoal from fall ing-out,
and to filter out radon progeny. 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 .
installed,in the home for up to seven days
according, to guidelines in the EPA protocols.
-------
At the end of testing, an adsorber Is reseated
and returned to the distributor or analytical
laboratory for processing and evaluation.
Advantages
Low cost for services; costs may range
froH $10 to $25.
Can be distributed by mall.
No special skills needed for making the
ieasurement.
Coapletely passive, needs no external
power.
With proper analysis, can yield precise
results.
Disadvantages
Scne charcoal adsorbers are more sensi-
tive than others to temperature and
hunidity.
United to short-tern testing.
Requires, as does any short-term meas-
urement , careful control of closed-
house conditions twelve hours before
and during the test.
Radon Prooenv Integrating Sampling Unlt-RPISU
(RP)
The RP method measures radon progeny. RP
detectors have a flow-rate air pump that pulls
air continuously through a detector assembly.
Depending on the node I, the unit can be in-
stalled 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 mail.
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.
May be limited to locations with AC
power.
Some units may 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 Radon (GR> and Grab Radon Progenv(GH)
The grab sampling methods measure concen-
trations of radon gas or radon progeny concen-
trations. The radon grab sample is collected
in as special flask holding 100 to 2,000 cubic
centimeters of air. The radon progeny grab
sample is collected by drawing air through a
filter, upon which progeny, if present in the
air, are collected. Both samples can be ac-
quired simultaneously with some detector sys-
tems. All sampling should be done in accor-
s
dance 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 work Ing-1 eve I tests (radon proge-
ny), 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 progeny
simultaneously.
Can acquire and evaluate several
samples per day.
Conditions during the measurement are
known to the operator.
Disadvantages
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 radon progeny, grab radon progeny
measurements are much more susceptible
to sampling error than radon gas
measurements.
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
instrtftjt-i'oiis 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 Follow-up Radon and Radon Decay
product Measurements". They must be accepted
by, and on file with, EPA by the end of the
follow-up test.
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, a
scheduled deadline will not be considered in
the performance evaluation process. A com-
pany's detector(s) must be tested every round
to maintain its proficiency listing.
