TECHNETIUM IN THE ENVIRONMENT. PROCEEDINGS OF A SEMINAR ON THE BEHAVIOUR OF TECHNETIUM IN THE ENVIRONMENT, JOINTLY ORGANIZED BY CEC, CEA, DEPARTMENT OF ENERGY (USA), HELD IN CADARACHE (F) ON OCTOBER 23-26, 1984.
Since the discovery of technetium (in 1937, by Perrier and Segre), technetium-99 and technetium-99m have become most familiar in the specialised literature, the behaviour of the former being of concern regarding its health impact, the latter having been used intensively in medical tests for many years. The knowledge of the characteristics and behaviour of this element in nature is currently increasing exponentially. It has become clear, however, that there is still a serious shortage of information needed to assess properly its burden and impact on man and his environment. Technetium may indeed be released from nuclear installations or as a waste product from medical applications. It is generally considered to be highly mobile as the anion TcO-4**-, but it is also suspected to be readily reduced in soils and metabolized in living beings into lower oxidation states. The seminar was planned to analyse thoroughly the experimental results obtained up to now and to make recommendations of specific issues requiring further research. This book presents the papers of the different sessions in the order of presentation, and the conclusions drawn by three discussion groups which dealt separately with: - problems of sources and distribution of man-made technetium and its radiological consequences; - the chemical behaviour of technetium in different ecosystems; - biochemical reactions and binding with macromolecules in various life systems. The publication of these proceedings enables the organisers of this seminar to draw attention to this specific element in the table of Mendeleev, with its multivarious and intensive utilisation in medical research, but with its paradoxically relatively unknown basic behaviour in the environment.
