Materials of radiation protection for shelters from ionizing radiation when handling experimental devices for a research nuclear facility IVV-2M

The description of the bench base of the research nuclear facility IVB-2M is given. The main stages of the life cycle of experimental devices intended for irradiation in a reactor are demonstrated. The importance of optimizing the content of the components of the radiation-protective material, determined by the isotopic composition of radioactive contamination, is shown, depending on the type of the reactor installation, the duration of operation, and other factors. The application of an optimization algorithm based on the results of a computational study of the attenuating power of homogeneous radiation-protective materials with various fillers relative to gamma radiation is described.Приведено описание стендовой базы исследовательской ядерной установки ИВВ-2М. Продемонстрированы основные этапы жизненного цикла экспериментальных устройств, предназначенных для облучения в реакторе. Показана значимость оптимизации содержания компонентов радиационно-защитного материала, определяемого изотопным составом радиоактивных загрязнений, в зависимости от типа реакторной установки, продолжительности эксплуатации и других факторов. Описано применение алгоритма оптимизации на основе полученных результатов расчетного исследования ослабляющей способности гомогенных радиационно-защитных материалов с различными наполнителями по отношению к гамма-излучению

HDV/AIDS awareness among young people and their sexual behaviour

This article presents the results of a survey carried out among 1,427 Novosibirsk university students (medical, engineering and humanities specializations) with the purpose of assessing their awareness concerning the prevention of HIV and STIs, as well as risky sexual behaviour. The level of knowledge about HIV is shown to be rather high among Novosibirsk university students. However, an insufficient level of awareness concerning rare HIV transmission routes is identified. In addition, the respondents are found to adhere to out-of-date views concerning HIV patients. Female respondents in this age group tend to trust their regular partner, thus neglecting preventive measures. More than half of the respondents have a positive attitude towards using a condom during sexual intercourse
