Development of multicomponent dosemeter for dosimetry of hot particles

The multicomponent thermoluminescent beta dosimeter developed is described. Calibration was realised using beta and gamma emitters. 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 Hp (10) corresponding to the hot particles found. A comparison between the calculated and the experimental values is presented. (Author)
