An exposure to 1 WL for 1 working month (170 hours) equals 1 WLM cumulative exposure. A cumulative exposure of 1 WLM is roughly equivalent to living one year in an atmosphere with a radon concentration of 230 Bq/m 3. [6] The radon (222 Rn) released into the air decays to 210 Pb and other radioisotopes. The levels of 210 Pb can be measured.
