Elemental Composition and Structure of Commercially Available Personal Radiation Shielding Protective Clothing

Popis výsledku v původním jazyce

Recently, the demand for personal protective equipment for radiation protection is increasing. The laboratory of SUJCHBO v. v. i. deals with a study of selected personal protection equipment properties. As a part of this research a collection of commercially available personal radiation shielding protective clothing (RSPC) was gathered at National Institute for NBC Protection. This protective clothing is a kind of protective garments used not only against radioactive contamination, but due to a special shielding layer RSPC protect against penetrating ionizing radiation as well. RSPC are possible to be used by special emergency response technical workers during accidents in nuclear facilities or by first responders and firemen in emergency situations such as accidents during radioactive material transportation, terrorist incidents involving radioactive dispersal devices or nuclear weapons. As a first part of the study there was determined X and gamma radiation attenuation in the materials of individual RSPC. During further research, it is intended to determine the effective dose to man using this protective garments and staying in a radiation field. This determination will be realized by Monte Carlo simulations using MCNPX code. For this purpose it is necessary to know the elemental composition of RSPC, especially the composition of the shielding layer. The elemental composition was determined by X-ray fluorescence analysis. The results were then refined using chemical analysis. In addition the material structure of RSPC was studied using electron microscopy. During the structure study, the elemental composition of shielding layers of selected shielding materials was determined using Energy-dispersive X-ray spectroscopy as well. In the contribution, the collection of commercially available RSPC will be presented with regard to their shielding material, their structure and methods of testing.
