摘要: Abstract At two points in the Postojna Cave, short-term monitoring summer and winter of air concentrations radon decay products, equilibrium factor, unattached fraction products ( f un ), barometric pressure, relative humidity cave temperature outdoor has been carried out, with emphasis on . Dose conversion factors, calculated basis values obtained (ranging from 0.09 to 0.65) exceed 5 mSv WLM − 1 , by a factor 11.5–14.0 3.0–4.0 for mouth breathing, 3.1–3.5 1.5–1.7 nasal breathing.
