A complex personal dosimeter including a gamma- and beta-ray dosimeter block and a neutron dosimeter block. These two blocks are enclosed in a badge case type package so that a person can secure the dosimeter on his clothing. The gamma- and beta-ray dosimeter block consists of four thermoluminescent elements in combination with plastic filters having different thickness. The neutron dosimeter block consists of four thermoluminescent elements in combination with cadmium and tin filters. This complex dosimeter can individually measure or estimate the radiation doses such as gamma-rays, beta-rays, thermal neutrons, epithermal neutrons and fast neutrons over a wide range of doses, and can also obtain information on the energy of the radiation.
