AN ELECTRET PHOTON DOSIMETER FOR RADIATION PROTECTION PRACTICE

The application of electret dosemeters in radiation protection practic e requires the reduction of environmental and handling effects that in jure the electret's charge stability. The charging procedure as well a s pre-and/or post-treatments of electrets must be optimised with the a im of good charge stability. Therefore, some change in the design of a previously developed dosemeter prototype and in the electret formatio n was undertaken. The results for long-term stability as well as the d osimetric properties of the new dosemeter type are described. Conclusi ons about its properties in comparison with those of the dosemeter pro totypes are drawn.
