Concept
The solution worked out at the GSI (Helmholtz Centre for Heavy Ion Research Darmstadt) is based on standard Harshaw-type TLD detector cards inset in a scattering body made from polyethylene. In two of the four crystals, copper is set as an additional filter. The combination of the measured dose of the two detector pairs leads to a response function, which bear a very close resemblance to the H*(10) measured value. This is achieved by two Cu-filters and allows its use in a very broad energy (10keV to 10MeV) and angular range.
Benefits • More accurate dose measurement in a very broad energy and angular range • Suitable for standard TLD cards • Compact and cost effective execution of the scattering body • Simple evaluation method • Easy handling • For outdoor use
