Interlaboratory Comparison of Different Alpha-particle and Radon Sources

Abstract

Alpha radiation-induced cell killing was determined in four different laboratories in order to: 1) measure interlaboratory variability and 2) compare the effects of radon and radon daughter exposures with the effects of 238Pu (an often-used model for radon exposure). The results suggest that differences in handling from laboratory to laboratory can affect both low and high linear energy transfer responses and should be considered when comparing results from different laboratories.
