We read with interest the paper “Radon survey in the kindergartens of three Visegrad countries (Hungary, Poland and Slovakia)” by Műllerová et al. . The authors have measured radon concentration in 67 rooms in kindergartens in Visegrad countries and reported that in 7.5% of rooms the concentration of radon exceeded the reference level of 300 Bq m−3. The annual effective dose due to inhalation of this level of radon was 0.5–13.3 mSv for children and 0.3–8.3 mSv for staff. Műllerová et al. state that “Moreover, radiation protection is based on the premise of linear no-threshold model. It means that the prognosis of lung cancer caused by radiation exposure depends on the duration of exposure. Therefore children exposed to the same dose than adults are more susceptible to lung cancer”. These claims are based on the linear-non threshold (LNT) hypothesis that assumes any radiation dose leads to a biological detriment and the effect of these exposures is cumulative [2, 3].
