Использование низкофоновой гамма-спектрометрии в Ð·Ð°Ð´Ð°Ñ‡Ð°Ñ ÑÐ´ÐµÑ€Ð½Ð¾Ð¹ криминалистики

Abstract

Ð’ процессе работы проводились экспериментальные исследования образцов, ÑÐ¾Ð´ÐµÑ€Ð¶Ð°Ñ‰Ð¸Ñ ÑƒÑ€Ð°Ð½ в разном изотопном соотношении. Изотопное соотношение было определено с допустимой погрешностью. Была создана ультра низкофоновая установка на базе подземной лаборатории «Радиевого института им. Ð’.Г. Хлопина» с Ñ Ð°Ñ€Ð°ÐºÑ‚ÐµÑ€Ð¸ÑÑ‚Ð¸ÐºÐ°Ð¼Ð¸, являющимися на сегодняшний день лучшими в России. С помощью данной установки проводились исследования для определения возраста урана. Возраст определен с большой погрешностью, требуется снижение фона Предложены пути дальнейшего снижения фона. Было принято участие в Ð¸Ð·Ð¼ÐµÑ€ÐµÐ½Ð¸ÑÑ Ð² Ñ€Ð°Ð¼ÐºÐ°Ñ Ð¼ÐµÐ¶Ð»Ð°Ð±Ð¾Ñ€Ð°Ñ‚Ð¾Ñ€Ð½Ñ‹Ñ ÑÐ»Ð¸Ñ‡ÐµÐ½Ð¸Ð¹ МАГАТЭ.
