Спектрометрія 90Sr в паливовмсних матеріалах
The paper presents a new technique to measure 90Sr in samples with high specific activity based on Kx-radiation. The probability of Kx-radiation during radioactive decay with the release of 90Sr and 90Y electrons was measured. The method to determine 90Sr in fuel-containing materials was proposed ac...

oai:ojs2.nuclear-journal.com:article-4112021-12-16T08:41:55Z Spectrometry of 90Sr in Fuel-Containing Materials Спектрометрія 90Sr в паливовмсних матеріалах Zheltonozhskaya, M. The paper presents a new technique to measure 90Sr in samples with high specific activity based on Kx-radiation. The probability of Kx-radiation during radioactive decay with the release of 90Sr and 90Y electrons was measured. The method to determine 90Sr in fuel-containing materials was proposed according to the data on the probability of atomic ionization in β-decay. 90Sr was measured in fuel fragments of various types. The results were compared and verified with radiochemical data. The proposed method allows 90Sr to be measured with an accuracy of 3-5% in the samples with high specific activity. These results offer new opportunities in the study of radioactive materials produced through nuclear fission. Розроблено новий метод вимірювання активності 90Sr в паливовмісних матеріалах без радіохімічного дослідження. Проведено вимірювання активності 90Sr в паливних частинках різного типу. Визначено ймовірність виникнення Кх-випромінення в процесі радіоактивного розпаду з випусканням електронів 90Sr та 90Y. Виконано порівняння з радіохімічними дослідженнями.
