Steinhausler (1987) and Martell (1987) review the dosimetric models and related model studies. Their view is that there are still very large uncertainties in the existing data and in the extrapolation from the exposure and response data for underground miners and experimental animals to the health effects of the radon progeny levels to which the general public is exposed. B.L. Cohen (1987) describes his work to relate radon measurements with lung cancer rates for various geographical areas to test the concept of a dose threshold. [Pg.11]

An additional unit of measurement used to describe human exposure to radon and radon progeny is the Working Level Month (WLM), which expresses both the intensity and duration of exposure. One WLM is defined as the exposure of a person to radon progeny at a concentration of 1.0 WL for a period of 1 working month (WM). A working month is assumed to be 170 hours. The S.l. unit for WLM is joule- hour per cubic meter of air (J-h/m ) 1 WLM is equal to 3.6x10 J-h/m. ... [Pg.22]
