A family of statistical distributions for modelling occupational radiation doses in low dose occupations.

abstract：:The HTR method, developed for determination of absorbed dose and average LET of mixed radiation fields in space, was applied during several space missions on space station MIR, space shuttles and satellites. The method utilises the changes of peak height ratios in the glow curves in dependence on the linear energy tra...
