101-105

In this work, the response of the Permanent Monitoring Station (PMS) was compared with the readings of environmental thermoluminescent dosimeters (TLD) based on high sensitive MCP-N (LiF:Mg, Cu, P) thermoluminecent detectors and Gamma Tracer, an active device. Thermoluminescent dosimeters were installed close to an automatic warning system of PMS and to a portable Gamma Tracer monitor which is used for long term, continuous measurements in the environment at the INP. For several weeks 137Cs, 60Co, 226Ra and 241Am gamma-ray sources have been placed at distances of a few meters from the dosimeters, in order to modify the radiation environment.

Limitations of thermoluminescent dosimeters in soft X-ray diagnostics of pulsed plasma

Responses of thermoluminescent dosimeters (TLDs) of CaF2:Dy, CaF2:Mn, and LiF:Mg,Cu,P to the deposited energy of monochromatic 1.75–3.5 keV radiation were measured with respect to an increase in the local dose due to the attenuation length that was much shorter than the TLD thickness. The responses of TLDs to X-ray emission from the laserproduced aluminium plasma were found to be independent of the dose rate within a wide range.
