INTRODUCTION
In 1974, the Idaho Department of Health and Welfare requested that the
Office of Radiation Programs-Las Vegas Facility (ORP-LVF) provide support in
sampling the air at five locations near the two phosphate plants in Pocatello,
Idaho.
From April 1974 through June 1975, the ORP-LVF evaluated the radiological
consequences of airborne effluents containing low levels of naturally occurr-
ing radioactive materials. In addition, "background" samples were obtained at
Howe and Arco, Idaho, from July through September 1977.
Reported here are the airborne concentrations of isotopic uranium and
thorium, and radium-226. Technical difficulties prevented the full assessment
of the radiological impact of polonium-210 and lead-210.
-------
SUMMARY AND CONCLUSIONS
Seven sites near Pocatello, Idaho were sampled and evaluated to determine
levels of several of the naturally occurring radionuclides in airborne
particulates. At the Pocatello Sewage Plant, airborne concentrations of
natural uranium (U-234, -235, and -238), radium-226, and thorium-230 were
found to be higher than the levels measured at the other sites and about an
order of magnitude greater than levels measured at Howe, the "background"
location. A correlation between the concentrations measured at the sewage
plant location and meteorological data indicates that emissions from the
phosphate plants caused the elevated levels in this area.
The other four locations in the Pocatello area are at least three miles
from the phosphate plants and are not in the predominant downwind direction.
Concentrations appear to be at background levels reported for Chicago and New
York City (NCRP, 1975) and are within about a factor of three of levels
measured at Howe. Moreover, uranium and radium concentrations measured at
Howe and Arco were about an order of magnitude less than the reported NCRP
"background" values, further indication that the airborne particulate radio-
activity near Pocatello exceeds the levels in the surrounding areas.
The impact of polonium-210 and lead-210 concentrations is not reported
here because technical difficulties were encountered during the radiochemical
analyses of these samples. Nonetheless, findings indicate a probable
significant radiological influence from these two radionuclides. To resolve
this issue, future studies should involve additional sampling and a thorough
evaluation of airborne polonium-210 and lead-210 radioactivity.

AIR SAMPLING PROGRAM DESCRIPTION
SAMPLING LOCATIONS
Figure 1 shows the five air sampling locations selected by the Idaho
Department of Health and Welfare (IDHW). The basis for choosing these sites
was either their proximity to population centers or the direction of the
prevailing winds relative to the phosphate plants. A brief description of
each site location follows:
#581 Hayes Fire Station 2, Pocatello (four miles southeast of
the plants)
#582 Pocatello Sewage Plant, Interstate 15W, Pocatello (one-half mile
northeast of the plants)
#583 NOAA Weather Station at the Pocatello Airport, Pocatello
(three miles west of the plants)
#584 Courthouse Building, Center St. and 5th Ave., Pocatello (five
and one-half miles southeast of the plants)
#585 The Chubbuck School, 5045 Hawthorne Road, Chubbuck, Idaho (thre~
miles northeast of the plants)
During the summer of 1977, the ORP-LVF made background airborne radio-
activity determinations in Howe and Arco, Idaho. Both communities are about
70 miles northwest of Pocatello and have no industrial activities that could
"technologically enhance" the amount of radioactivity in their environment.

SAMPLER DESCRIPTION AND OPERATING PROCEDURES
The IDHW conducted volume particulate air sampling using heavy duty air
samplers (Research Appliance Corp., Allison Park, PA; or Tempest Air Sampler,
Gelman Instrument Corp., Ann Arbor, MI) that ran continuously without
requiring routine maintenance.
Each sampler has a carbon-vane pump driven through a V-belt system by a
110 volt, 3/4 hp motor with overload protection, and a free flow capacity of
10.5 cubic feet per minute (CFM). Each unit has a built-in vacuum gauge,
individually calibrated for pressure drop versus air flow rate. A cumulative
time-meter, reading to tenths of an hour, provided total elapsed sampling
time. The air volume passing the filter was determined by averaging the "on"
and "off" flow rates and multiplying by the total elapsed time for the
sampling period. A quick-change 110-mm-diameter filter holder was mounted one
meter above ground and was secured so that the open face of the filter was
toward the ground. The filters (Gelman Type E, 102-mm (4-inch) diameter glass
fiber) were changed weekly.
The sampling period for three of the five stations extended from April 5,
1974 to June 20, 1975. Sampling site #585 operated only through August 22,
1974, and site #584 operated through November 4, 1974.
ANALYTICAL PROCEDURES
ORP-LVF analyzed each filter radiochemically at the U.S. EPA-Environmental
Monitoring and Support Laboratory (EMSL) for radium-226, thorium-230, and
-232, and uranium-234, -235, and -238. Standard radiochemical procedures
(Johns, 1975) were used.
Radiochemical analyses for polonium-210 and lead-210 indicate that concen-
trations of these radionuclides may have a significant radiological impact;
however, technical difficulties encountered during the analyses prevent
ORP-LVF from reporting its determinations here. These difficulties are
discussed in two previous ORP-LVF reports on the Idaho phosphate industry (EPA
-------
1977 and 1978). A thorough evaluation focusing on the polonium and lead
concentrations will have to wait for another sampling because the air filters
collected during this study were consumed during analysis. However, a similar
study (U.S. AEC, 1970) indicates that the polonium-210 content averaged about
88 percent of the gross alpha radioactivity measured on air samples collected
in the Pocatello area in 1969-70.
In 1976, Eadie and Bernhardt reported the radioactivity analysis of blank
Gelman Type E glass fiber filters. They also described methods for blank
subtraction of composite samples, standard deviation determination of net
results, and volume weighting of monthly averages. ORP-LVF obtained the
sample net activity for this study by subtracting the average blank filter
content from the measured gross analytical result.
METEOROLOGICAL MEASUREMENTS
Meteorological data for the Pocatello area were prepared by the U.S.
Department of Commerce, National Oceanic and Atmospheric Administration
(NOAA), Environmental Data Service. Measurements cover one year beginning
April 1, 1974. The weather station is located at the Pocatello Airport
(Station #24156). Data are based on eight observations per day.
Figure 2 shows the 12-month average wind rose. Each bold faced number in
a sector refers to the percentage of total time the wind was from the
direction indicated and was between the velocities (mph) defined at the
interface of each concentric circle along the north axis. Look, for example,
at the ENE sector; the wind was blowing 18 to 24 mph towards the WSW less than
0.05 percent of the time, 13 to 18 mph 0.2 percent of the time, and 4 to 13
mph 2.5 percent of the time over one year. The figure in the center indicates
a calm of 0 to 4 mph and is considered nondirectional.
-------
RESULTS AND DISCUSSION
Table 1 summarizes the study data. Appendix A shows the composite monthly
airborne particulate radioactivities at each sampling station, as well as the
grand volume weighted average of monthly results and the associated standard
error of the mean based on the t-distribution at the 95 percent confidence
level.
All results represent ambient airborne concentrations (natural background
levels have not been subtracted). For some of the air samples, dust particu-
late loading was determined by measuring the mass of dust collected on each
air sample filter. Appendix B shows the specific activity of the dust. The
solubility of the airborne particulate material was not determined.
Figure 3 shows the average concentration (pCi/m3) of each radionuclide
by location for the entire sampling period. Stations are arranged in
geographical order, relative to the phosphate plants, from west to east-
southeast. The relative percentage of time each station was downwind from the
plant location is noted at the top of each set of bar graphs for a given
station location. Station #582 (the sewage plant), predominantly downwind,
had the highest airborne concentration of radioactivitythe levels are about
an order of magnitude greater than levels measured at Howe, the "background"
location. As shown in Figure 3, the measured concentrations at the sewage
plant appear to correlate with meteorological data, indicating that these
levels were probably due to emissions from the two phosphate plants.
The other four locations in the Pocatello area are at least three miles
from the two phosphate plants and are not in the predominant downwind direc-
tion. Concentrations appear to be at background levels reported for Chicago
and New York City (NCRP, 1975) and are within about a factor of three of
levels measured at Howe. Moreover, uranium and radium concentrations measured
at Howe and Arco were about an order of magnitude less than the reported NCRP
"background" values, further indication that airborne particulate radio-
activity near Pocatello exceeds the levels in the surrounding areas.

DOSE ESTIMATES
Defining natural background levels of airborne concentrations of specific
radionuclides in the Pocatello area is difficult. The National Council on
Radiation Protection and Measurements Report No. 45 (NCRP, 1975) summarized
natural background airborne levels for several radionuclides at diverse
geographic sites. These levels appear in Table 1. For this study, the
measured airborne concentrations of uranium and radium-226 at the two
background locations (Howe and Arco) are roughly an order of magnitude less
than the NCRP-reported background values. However, the thorium concentrations
measured at Howe and Arco are greater (but within a factor of two) than the
NCRP background estimates for thorium levels.
In order to establish the "above background" concentrations for the five
locations in Pocatello, the measured results from Howe have been subtracted
from the ambient results. Table 2 shows the resultant "net concentrations."
Table 3 lists the dose conversion factors for each radionuclide measured
in this study. (The doses due to radium-228, polonium-210, and lead-210 have
not been estimated because these radionuclides were not evaluated for this
study.) These factors represent the average annual dose equivalent in rems
for each year of chronic inhalation at a concentration of 1 pCi/m3. Dose
estimates have been maximized by assuming that the indoor airborne concen-
trations would equal the measured outdoor ambient levels. The highest total
dose of 10 millirem was calculated for an individual exposed to the annual
average ambient radionuclide concentrations measured outdoors at the sewage
plant (assuming a continuous exposure for the entire year at the average
ambient values as reported in Table 1). Similarly, a total dose of less than
1 millirem was calculated for an individual exposed to the annual average
ambient radionuclide concentrations measured outdoors at Howe the location
having the lowest measured airborne concentrations. Therefore, considering
Howe as representative of "background" conditions, the maximum additional dose
(above background) to an individual in the Pocatello area would be about 9
millirem for each year of exposure to airborne radionuclide concentrations as
measured during this study.

However, the major dose would probably be due to the inhalation of
elevated concentrations of polonium-210 and lead-210, based on previously
reported data (U.S. AEC, 1970) indicating that the majority of alpha
radioactivity (i.e., 88 percent) was due to the polonium-210 content.

particulate radioactivity levels of naturally occurring radionuclides were
measured at seven sites near Pocatello, ID. At one of the sites (Pocatello Sewage Plant)
airborne concentrations of natural uranium, radium-226, and thorium-230 were found to be
higher than the levels measured at the other sites and about an order of magnitude
greater than levels measured at the "background" location at the village of Howe. There
appears to be some correlation between the measured concentrations at the sewage plant
and meteorological data to indicate that the measured levels were probably due to e
