Abstract
Nuclear energy and its derivatives have long been the subject of considerable debate. Tritium, or H3, the lightest of all radionuclides, is usually the single largest radioactive substance emitted as a part of normal nuclear power plant operations. Because H3 is a low energy beta emitter it is often discounted as a threat to biological systems. Given the planned release of 1.3M tons of tritiated water to the Pacific Ocean at the Fukushima Daichi Nuclear Power Plant, there is great interest concerning what is known concerning its effects on biological systems, including humans.

As a first step towards addressing these concerns, we have generated a database of the scientific and grey literatures based on studies that might have some bearing on this issue. Using ISI’s Web of Science, Google Scholar, and EBSCO Academic Search Complete, we scanned over 700,000 references to tritium to arrive at about 250 studies that addressed some aspect of its biological consequences. The first conclusion from this review is that there is surprisingly sparce coverage of a topic of such great concern to so many. There are no published studies of tritium effects on human cancers, and very few of tritium effects in natural systems. The vast majority of studies of tritium effects have been conducted using laboratory organisms, making extrapolation to natural conditions tenuous. Our second conclusion is that contrary to some popular notions that tritium is a relatively benign radiation source, the vast majority of published studies indicate that exposures, especially those related to internal exposures, can have significant biological consequences including damage to DNA, impaired physiology and development, reduced fertility and longevity, and can lead to elevated risks of diseases including cancer. Our principal message is that tritium is a highly underrated environmental toxin that deserves much greater scrutiny.

Traduction de la dernière phrase du résumé "Contrairement à la pensée courante que le tritium est une source de radiation relativement bénine, la majorité des publications indique qu'une exposition, particulièrement celles internes, peuvent avoir des conséquences biologiques significatives incluant des dommages à l'ADN, ???, réduction de la fertilité et de la longévité, et peuvent augmenter le risque de dégats incluant des cancers. Notre principal message est que le tritium est une toxine sévère dans l'environnement qui fait des dégats sévères dans l'environnement??"

Ils sont décontamineurs ou « jumpers » : en un « saut » au cœur des installations nucléaires, ils peuvent absorber de fortes doses de radioactivité. Indispensables au bon fonctionnement des centrales, ces milliers (...)
