Palaeodosimetric methods of dating, especially the OSL method, are now capable of dating very recent sediments, that if formed within the last 100 years, experienced a contribution to the absorbed dose from the fallout radioisotopes, the contribution that forms a significant portion of the total absorbed dose. The paper presents results of calculations of this contribution from the radioisotopes other than 137Cs and finds it of approximately the same magnitude as dose received from 137Cs alone, meaning that it should be taken into account in the case of high precision dating of recently formed sediments.
