RTG已为许多太空任务提供动力，包括美国宇航局的“卡西尼号”和“新视野”探测器。在放射性物质的小球衰退过程中可以产生出热量，从而将其转化为电能。
RTGs power many space missions — including NASA's Cassini and New Horizons probes — as the slow decay of small pellets of radioactive material produces heat that can be turned into electricity.
同时，由于使用了非放射性技术，因此M4JCAD比上一代探测器更具优势。
It also benefits from the use of a non-radioactive technology compared with previous generations of detectors.
为了探测质子衰变放射性的假想形式，人们修建了巨大的探测器，但这些探测器从没发现这种东西。
Giant detectors built to look for a hypothetical form of radioactivity in which protons decay never found such a thing.
而放射性同位素能量源可以为探测器提供热量和电能。
A radioisotope power source will provide heat and electric power to the rover.
对于在放射性核素测量中可能遇到的较强源带来的较大探测器死时间问题进行了研究，找到了进行死时间修正的方法。
A problem, which causes the biggish detector dead time during the biggish power experiments, is discussed. A method used for dead time correction is found.
自然伽马测井是套管井测井中一种最基本的方法。它以地层自然放射性为基础，测井时用伽马射线探测器沿井眼进行测量。地层中的自然伽马放射性不是一成不变的。
Natural gamma logging is a kind of most basic methods of well logging in cased Wells which measure with gamma ray detector along well during logging.
