放射衰变 meaning in Chinese

emission decay
radio active decay
radioactive decay

A new type of battery based on the radioactive decay of nuclear material is 10 times more powerful than similar prototypes and should last a decade or more without a charge , scientists announced
一种以核子物质放射衰变为基础的新型电池，电力比类似的原型强上十倍，在不充电的情况下应可维持十年以上，科学家宣布。
Rather they were the products of the decay of radioactive isotopes of iodine , which in turn were formed from radioactive tellurium and so forth , according to a well - known sequence of nuclear reactions that gives rise to stable xenon
它们其实是碘同位素放射衰变的产物，而碘是由放射性碲产生，依此类推，经由人们所熟知的一系列核反应而产生稳定的氙。
Although almost all this material , which has a 24 , 000 - year half - life , has since disappeared ( primarily through natural radioactive decay ) , some of the plutonium itself underwent fission , as attested by the presence of its characteristic fission products
这些物质半衰期为2万4000年，几乎已经全部消失（主要是经由自然的放射衰变过程），而且部份的钸本身又经过核分裂，这可由其核分裂产物为证。
