Hot particle dosimetry at nuclear power plants

Abstract Calibration and analysis of data obtained from a multicomponent thermoluminescent beta dosemeter are described. Measurements of directional equivalent dose rate of beta radiation and effective beta energy were carried out in the working environment of a nuclear power plant (Vandellos II) by means of thermoluminescent detectors. The effective beta energy ranges most frequently between 150 and 500 keV . The last version of the VARSKIN MOD 2 code has been used to calculate the directional dose equivalent rate H ′(0.07,0) and the personal dose equivalent rate H p (10) corresponding to the hot particles found. A comparison between the calculated and the experimental values is presented.
