title: Calculations on the relationship between gamma source distributions in the soil and external doses.
abstract: Calculated activity concentration to free-in-air kerma conversion factors are given for natural emitters distributed differently in the soil. Dose modifying effects of snow and concrete covers are also studied. Finally, air-kerma to effective dose equivalent conversion factors are calculated for anthropomorphic phantoms.
