Features of Radiological and Biological Actions of ¹⁴C on Living Organisms and the Danger of its Accumulation in the Earth's Biosphere

Interest in ¹⁴C is increasing in connection with its accumulation in the Earth's biosphere. Participating in exchange processes as a biogenic analog of stable carbon it penetrates into all organs and tissues of living organisms. The danger of its accumulation in the Earth's biosphere is determined by a particular feature of the damaging action incorporated in living organisms. These particularities and as a result the danger for mankind and individual groups of the population living in regions containing sources of ¹⁴C are briefly examined in this article.
