The Contribution of Eurados and Cendos to Track Etch Neutron Dosimetry: The Current Status in Europe

A joint UAB-IReS-IPNO neutron comparison exercise with nuclear track detectors

“…The results for the UAB and IReS groups were in good agreement with those obtained by Luszik-Bhadra et al (1994), Luszik-Bhadra et al (1992) and Harvey et al (1998).…”

“…To determine the minimum detectable dose equivalent (MDDE) for the three dosemeters, we have used the expression given at the 97.5% level of confidence by Harvey et al (1998). For the UAB group taking into account all the irradiation runs, a mean value of MDDE = 52 ± 25 Sv was obtained.…”

“…In this situation, passive dosemeters based on activation (Followil et al, 2003), nuclear track (Králik and Turek, 2004) or thermoluminescence (Holeman et al, 1977) detectors seem to offer a very satisfactory solution. In this sense, nuclear track detectors, for instance PADC (poly allyl diglycol carbonate) polymer plastics, are the most promising since they are insensitive to photons and they do not require expensive or complicated experimental instrumentation (Harvey et al, 1998).…”

The new PADC based fast neutron dosimetry system of the INFN—LNF

“…4. As indicated by Harvey et al (1998), the frequency distribution has a log-normal shape, with a significant fraction of dosemeters which track density is considerably higher than the average ("hot spots"). The most popular techniques to reduce the fraction of false positives due to these hot spots and, consequently, the MDDE of the dosimetry service, are:…”

“…It should be noticed that in a single dosemeter analysis, according to the Harvey et al (1998) formulation, the MDDE should be calculated with the following formula:…”
