Type tests of an extremity ring dosemeter provided by a Brazilian dosimetry service

Data concerning calibration and type tests of an extremity system based on XD100 rings (Harshaw) are presented. Dosemeter used was a thermoluminescent chip inserted in a sealed pouch and was read out using a Harshaw 6600 read er. Aiming to reduce the lower detectable dose and to improve reproducibili ty of response, two different methods of analysis were carried out and comp ared. The first performed a background correction based on an average value obtained from the evaluation of a group of non-irradiated dosemeters and m anually subtracted. The second method employed a glow curve deconvolution a lgorithm. The dosimetric system complied with all ISO/DIS 12794-1 draft rep ort suggested tests, on which this work was based. This work obtained resul ts that point to the applicability of those recommendations to Brazilian in stitutes and suggest their adoption by the national regulatory commission.
