Il y a 2 jours · Krypton 93, Baryum 140, Xénon 133 ou encore Césium 137 et Strontium 90 … il existe une très grande variété de produits de fission, certains plus radioactifs que d’autres, certains avec une période radioactive plus longue que d’autres, pouvant aller de quelques heures à plusieurs millions d’années.
2 juil. 2024 · Néanmoins, ce processus est extrêmement lent et le césium 137 et le strontium 90 continuent à migrer verticalement dans le sol de 2 à 4 centimètres par an, rencontrant des racines qui peuvent faire remonter ces éléments radioactifs.
26 juin 2024 · Conducted from 1956 to 1989, the strontium-90 ingestion study followed roughly 460 beagles throughout their lifespans after they were exposed to strontium-90 in utero (through feeding of the mother) and fed strontium-90 feed at varying doses from weaning to age 540 days.
26 juin 2024 · This is a list of radioactive nuclides (sometimes also called isotopes ), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds. [1]
18 juin 2024 · Under the MOU, SHINE plans to provide Zeno with strontium-90 to power its RPSs, which are capable of providing continuous power in harsh environments. According to SHINE, the partnership is a significant step forward in the company’s Phase 3 initiative to recycle and reuse spent nuclear fuel.
24 juin 2024 · SHINE plans to provide Zeno with strontium-90 (Sr-90) to power RPSs for national security, scientific exploration, and commercial applications in frontier environments. Sr-90 is a byproduct of nuclear fission and a major contributor of heat and radioactivity in used nuclear fuel.
20 juin 2024 · Strontium-90, which is structurally similar to calcium and attaches to bones and teeth after being ingested, is known to cause cancer.
