[Whole Body Radiation Counter] Very sensitive device intended to measure even the smallest amount of radionuclides in the entire body. Range usually from Bq to kBq. Heavy shielding is used to keep out naturally existing background radiation.

The dose limit is the highest value of an applied or allowed radiation exposure. The radiation dose is limited in order to prevent the occurrence of radiation-induced deterministic effects or to limit the probability of radiation-related stochastic effects to an acceptable level.
