PURPOSE:To easily evaluate the effective dose equiv. in an arbitrary radiation field by providing an energy-angle dependent radiation flux measuring instrument, a memory device for the in-organ tissue dose equiv. conversion value of the unit radiation dose dependent upon radiation kind-energy-angle fluxes, a dose equiv. calculator, and an effective dose equiv. calculator. CONSTITUTION:The energy-angle dependent radiation flux measuring instrument 1 measures the energy and angle dependent radiation fluxes for each of the respective kinds of the radiations and inputs the same to the dose equiv. calculator 2. The dose equiv. calculator 2 calculates the dose equiv. of the respective organ tissues by the in-organ tissue dose equiv. conversion value of the unit radiation dose dependent upon radiation kind-energy-angle fluxes from the memory device 3 for the in-organ tissue dose equiv. conversion value of the unit radiation dose dependent upon radiation kind-energy-angle fluxes. The effective does equiv. calculator 4 multiples the dose equiv. by the load coefft. stored in a load coefft. memory device 5 and calculates the effective dose equiv. by summing the same.
