“…The results on the V b determination are shown in Figure 1. The graph shows the removed layer as a function of the etching time, confirming the linear trend expected for each material (excluding a nonlinear region in the beginning of the etch or ~25 min (6,7) ). The TASTRAK and RTP 0.1% are the 'softest' tested materials, with a V b of 14 and 12.8 μm/h, respectively (Table 2), i.e.…”

The objective of this study was to compare poly-allyl diglycol carbonate (PADC) track detectors from different suppliers for linear energy transfer (LET) spectrometry and neutron dosimetry. PADCs are commonly used for passive personal neutron dosimetry, where a common approach is to couple the PADC with a plastic radiator to generate secondary charged particles. The neutron dose can be estimated using the track density or the average LET of the secondary particles. The characterisation of PADC in terms of LET spectrometric capability and neutron sensitivity was previously performed using PADC from Intercast S.r.l., Parma, Italy, but this company stopped the production. Since it is common experience that material from different suppliers can have different properties, it became necessary to perform a comparison of PADCs from different suppliers with the Intercast material. The study permits to compare the reading procedures used at Politecnico di Milano and at the Paul Scherrer Institute.

“…A quality control programme is provided in order to guarantee the constancy of experimental parameters. The temperature and concentration of the solution during the etching process were monitored using a temperature probe integrated in a WTW conductivity meter (Inolab 740, WTW) [21]. This programme requires that the KOH blank solution has a conductivity of 550 ± 5 mS cm −1 at the reference temperature of 20 • C; this value corresponds to a concentration of 5.4 M. During the etching process a variation of conductivity not higher than 2% is tolerated.…”

Etched track detectors are widely used for the detection of radon and its decay products. The reliability of radon measurement performed with such devices requires that laboratories producing analytical data are able to provide results of the required quality. The need for uniform results from laboratories at an international level therefore requires the implementation of a quality assurance programme, the harmonization of criteria, sampling procedures, calculations and the reporting of results, agreed on the basis of fundamental principles and international standards. The quality assurance programme described here is the first step on the way to ISO/IEC 17025 certification for the RI-RN (ISPESL) laboratory.
