Complex personal dosimeter

Claim 1

A complex personal dosimeter including a gamma- and beta-ray dosimeter block and a neutron dosimeter block, these two blocks being enclosed in a package of a badge case type, said gamma- and beta-ray dosimeter block consisting of: a first dosimeter unit for measuring the dose of beta-rays comprising a first thermoluminescent element sensitive to gamma- and beta-rays, with a first filter for partially screening beta-rays disposed on the front side of said first element; a second dosimeter unit for measuring beta-ray energy comprising a second thermoluminescent element sensitive to gamma- and beta-rays, with a second filter disposed on the front side of said second element, said second filter being thicker than said first filter; a third dosimeter unit for measuring the dose of gamma-rays comprising a third thermoluminescent element sensitive to gamma-rays and having an energy response suitable for determining the depth dose equivalent index; and a fourth dosimeter unit for measuring gamma-ray energy comprising a fourth thermoluminescent element sensitive to gamma-rays; said neutron dosimeter block consisting of: a fifth dosimeter unit for compensating a gamma-ray contribution in the determination of the neutron dose, said fifth unit comprising a fifth thermoluminescent element sensitive to gamma-rays with filters of cadmium disposed on both front and rear sides of said fifth element; a sixth dosimeter unit comprising a sixth thermoluminescent element sensitive to neutrons and gamma-rays with a filter of tin and a filter of cadmium disposed on the front and rear sides, respectively, of said sixth element; a seventh dosimeter unit comprising a seventh thermoluminescent element sensitive to neutrons and gamma-rays with filters of cadmium disposed on both front and rear sides of said seventh element; and a eighth dosimeter unit having the same construction as that of said sixth dosimeter unit but in the opposite arrangement of said tin and cadmium filters.
