Abstract :
Animals that breed in ground holes can be exposed to higher doses of radiation from natural
radioactive isotopes, including radon and its daughters, present in soil air. One of such species is the Sand Martin
Riparia riparia. Examination of natural burrows in sand mines revealed radon levels of 2.82-1320 Bq/m3 in the
examined soil horizon where martins dug their burrows. It was shown that adult males whose colonial breeding
took place in sand mines received the following average annual doses, respectively: 4.7 mGy (during the care for
one brood) and 8.8 mGy (two broods). The doses for females were, respectively: 4.7 mGy (one brood) and 8.7
mGy (two broods). At the same time, the average dose to chicks from these colonies was 6.4 mGy. The results
indicate that, apart from radon concentrations in the soil, also breeding behaviour – rearing either one or two
broods – significantly affects the annual absorbed radiation dose to adult birds.
