DORIS H*(10) Dosimeter case
for rados or harshaw tld-cards
DORIS = DOsimeteR for Indoor and outdoor Surveys
The solution worked out at the GSI Helmholtz Centre for Heavy Ion Research GmbH is based on standard Harshaw-type TLD detector cards placed inside a scattering body made of polyethylene.
Placed inside the dosimeter, two out of four crystals of the TLD card are shielded by a thin copper foil acting as a filter. The combination of the dose measurements of the two detector pairs leads to a response function which very closely resembles the H*(10) measure. The two Cu-filters make possible dosimetry in a very broad energy (10keV to 10MeV) and angular range.
These characteristics represent a significant improvement compared to commercially available solutions. Standard solutions follow the H*(10) function only in a much smaller energy range from about 100keV to 1MeV. As a result of its special design, the dosimeter can be used under almost all weather and environmental conditions.
