About: Long-lived fission product

An Entity of Type: company, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Long-lived fission products (LLFPs) are radioactive materials with a long half-life (more than 200,000 years) produced by nuclear fission of uranium and plutonium. Because of their persistent radiotoxicity it is necessary to isolate them from man and biosphere and to confine them in nuclear waste repositories for geological period of times.

  • Long-lived fission products (LLFPs) are radioactive materials with a long half-life (more than 200,000 years) produced by nuclear fission of uranium and plutonium. Because of their persistent radiotoxicity it is necessary to isolate them from man and biosphere and to confine them in nuclear waste repositories for geological period of times. (en)
  • Les produits de fission à vie longue sont les matériaux radioactifs dont la demi-vie est longue (plus de 200 000 ans), produits par fission nucléaire. (fr)
  • 長壽命裂變產物一般指由核裂變反應产生的、半衰期超過20萬年的放射性物質。這並非精確的科學定義，比如有人把某些半衰期在20年至100年間的裂變產物也稱作長壽命裂變產物。另外的人則主張把這些半衰期在20年-100年間的裂變產物稱作中等壽命裂變產物。 (zh)
