title: Concentrations of radon and its progeny in the rooms of Polish spas.
abstract: Radon concentrations and radon-daughter exposures of workers have been determined in three Polish spas where radon is used as a therapeutic agent. A wide range of values for both parameters was observed during the late 1970s, with some exposures above the annual limit of 3.5 WLM, particularly among technical personnel at a spa using uranium ore as a source. A downward trend in these exposures in recent years reflects the effect of improved practices.
