Abstract:
1. A readable credit card sized citizen's dosimeter for measuring radiation dose of record comprising: a lower card layer, the lower card layer having an inner and outer side, and a first aperture; a upper card layer, the upper layer card having an inner and outer side; an optically stimulated luminescent material (OSLM), the OSLM positioned between the inner side of the lower card layer and the inner side of the upper card layer during radiation measurement; energy compensation filters attached to the outer sides of the lower and upper card layers, and; a shutter means for exposing at least one side of the OSLM to the first aperture of the lower card layer for readout, wherein the shutter means covers the first aperture when the shutter means is in the closed position during radiation measurement, and exposes the OSLM to the first aperture when the shutter means is open during readout, wherein the upper and lower card layers are made of stainless steel, the stainless steel acting as an electronic equilibrium filter, and wherein the energy compensation filters comprise Tantalum.
