Dosimetry and radiation stability

Summary:

The work with ionizing radiation is associated with its hazardous effects on the body. Such effect must be controlled. The value of absorbed, equivalent or effective dose is used for this purpose. Materials capable to store energy in the form of structural defects and then radiate it when heated are used to assess the dose. This method is called thermoluminescence dosimetry. Our laboratory is developing and studying such materials.

An important property of materials used in nuclear and space technologies is their radiation stability. Therefore, no matter how promising is a material/molecule/component in terms of its physical or chemical properties, application becomes impossible if its radiation stability is low. In our laboratory, we investigate the properties of organic and inorganic materials (by gamma-ray irradiation) and work on the development of methods for theoretical prediction of materials’ radiation stability.
