Radiation doses received by small mammals inhabiting a dry radioactive leaching pond on the Idaho National Engineering Laboratory Site in southeastern Idaho were determined by surgically implanting lithium fluoride thermoluminescent dosimeter (TLD) chips. One hundred eightytwo TLD packets were implanted in 3 species: white-footed deer mouse (Peromyscus maniculatus), least chipmunk (Eutamias minimus), and Ord's kangaroo rat (Dipodomys ordii), with 65% recovery.All species from the radioactive leaching pond received significantly greater (P < .001) doses than control species. The deer mice received a mean dose equivalent rate of 160 mrem/day which was significantly greater (P < .001) than the mean dose equivalent rates received by least chipmunks (17 mrem/day) and Ord's kangaroo rats (6 mrem/day). The mean dose received by deer mice was 8% of the maximum air exposure recorded near the ground surface of the leaching pond. The maximum dose rate received by an individual deer mouse was nearly 50% of the maximum exposure rates in the study plot.Interspecific dose differences appeared to be related to habitat preference. Deer mice were most frequently captured on the gravelly and sparsely vegetated dry pond bed which had site exposure rates of 200 to 2000 mRoentgen/day. Conversely, chipmunks and kangaroo rats were usually captured on the pond banks which were adjacent to areas with sandy soil and denser vegetation. Site exposure rates on the pond banks ranged from 10 to 30 mRoentgen/day. Doses received by individuals of each species had high variation which appeared to be caused by the variable air exposure rates and the mobility of the small mammals. Intraspecific differences in activity, behavior and home range may have also influenced the dose variability in individual rodents.The advantage of implanted TLD over externally attached TLD and possible radiation effects on small mammal populations are discussed.

Chronic exposure to gamma radiation of wild populations of meadow voles (Microtus pennsylvanicus)

“…Animal dose rates were determined with collars containing three TLD-100 chips inserted between an electrical cable clasp and heat shrinkable tubing, after consideration of the options available at the time (Halford and Markham, 1978). Collars were applied to a random sample of animals at every second capture.…”

Radiocesium Concentration in Migratory Birds Wintering in Spain After the Chernobyl Accident

“…These comparisons were made using Bonferroni t tests (Miller 1966) conducted on the logarithms of the ratios. et al (1987), Halford (1987), Hakonson and Bostick (1976), Little (1980) and Garten (1981) for small mammals collected in various habitats. The GM GI-over-pelt ratios were all greater than one, and the GM GI-over-pelt ratio for 137Cs was statistically larger than those for the other radionuclides by a factor of four or five.…”

Guidance Manual for Conducting Screening Level Ecological Risk Assessments at the INEL

“…This suggests significant contamination from the site is not transported far from the site. Halford (1983). Deer mice, Oral's kangaroo rats, western harvest mice (Reithrodontornys nzegalotis), and Great Basin pocket mice were the most common small mammals at a liquid radioactive waste disposal area cm the INEL.…”

“…Doses received by individual, nonhuman organisms provide a basis for determining the potential for harm to populations. A number of authors have calculated or estimated doses to nonhuman organisms from internal and external contamination received at the INEL Fraley et al 1982;Halford 1987a;Halford 1987b;Markham et al 1988;Morris et al in preparation). found that some maximally exposed small mammals inhabiting the TRA radioactive waste pond basin received doses that had been found to reduce life expectancy in earlier studies .…”
