| Description
| - Some samples of personal radiation shielding protective equipment were tested at the National Institute for NBC Protection, Czech Republic in a Radon-aerosol chamber (RAC), which enables direct testing of protective equipment in a radioactive aerosol atmosphere. Main used radionuclides, depositing on non-radioactive aerosol particles into the RAC, were short-term radon decay products, or short-term radionuclides with stable decay products (99mTc, 140La, 24Na ...). Absorbed dose has been measured by TLDs (LiF: Mg Cu, P) and determined by an analyser Harshaw 3500 (producer: ThermoScientific, USA). TLD holders were placed uniformly under and on the surface of individual radiation shielding protective equipment, placed on a testing mannequin, and on covering personal protective clothing against radioactive aerosol contamination. Gamma (and beta) rays attenuation was determined from dose mean values in corresponding parts of protective equipment. Together with testing radiation shielding protective equipment in the RAC the attenuation of gamma rays, penetrating the samples, was tested via different radionuclide point sources, using a testing bench, which enables to set defined geometries of the source, the sample, the detector and the collimators separately. The spectra were measured by hand – held spectrometers HPGe FALCON 5000 or INSPECTOR 1000 with a scintillation probe IPROL-1 (producer of both spectrometers: CANBERRA, USA). Dose rate was measured by a radiometer FH 40 G-10 with a detachable probe FHZ 612-10 as well. For each sample and each radionuclide dose rate decrease, shielding ratio and energy dependence of linear and mass attenuation coefficients were determined. The results for different geometries and different methods of measurement (dose rate decrease and gamma rays attenuation for corresponding energy) were compared.
