The origins of non-Poisson random errors during calibration are different for different kinds of instrumental measurements. The main sources of uncertainties for retrospective measurements conducted by surface traps techniques can be divided in two groups: errors of surface (210)Pb ((210)Po) activity measurements and uncertainties of transfer from (210)Pb surface activity in glass objects to average radon concentration during this object exposure. It's shown that total measurement error of surface trap retrospective technique can be decreased to 35%. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
