BCL-2-MBR/J_Htranslocation–carrying cells in NPP workers and in healthy controls.

Total number of circulating BCL-2-MBR/J_Htranslocation–carrying cells in t(14;18)-positive healthy males working at a nuclear power plant (▴) grouped according to their cumulative radiation exposure (see Table 1) and age-matched healthy controls (○). There were no significant differences between NPP workers and healthy controls as well as their subgroups, A to D (Mann Whitney test; all positive individuals: P = .19; subgroup A, P = .45; B, P = .15; C,P = .46; D, P = .51).
