Element 43's radioactivity makes it easy to isolate and measure.───43号元素的放射性使其易于分离和测量。
Born Maria Sklodowska in Poland in 1867, she is famous for her work on radioactivity, and was twice a winner of the Nobel Prize.───她于1867年出生在波兰，原名玛丽亚·斯克洛多夫斯卡，以放射性研究而闻名，曾两次获得诺贝尔奖。
Both won the Nobel Prize and had Leukemia because of radioactivity.───两人都获得了诺贝尔奖，并因为放射性而得了白血病。
Some of that radioactivity could carry in the atmosphere to the west coast of the United States.───某些核辐射可能通过空气传播到美国西海岸。
There was no inkling of the size of the universe beyond the Milky Way, and radioactivity, relativity and quantum theory were unimaginable.───人们对银河那边存在的宇宙究竟有多大一无所知，辐射能、相对论和量子论更是想都不敢想的问题。
Giant detectors built to look for a hypothetical form of radioactivity in which protons decay never found such a thing.───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。
This led her to deduce that there were other substances within pitchblende that had properties of radioactivity.───于是玛丽推断出，在沥青铀矿中可能还有其他具有放射性的物质。
Though it was more likely that these events were due to cosmic rays or radioactivity, the results were consistent with a detection of WIMPs.───虽然它更有可能是这些事件是由于宇宙射线或放射性物质，其结果与一个懦夫检测一致。
The Navy says the submarine's nuclear reactor was not damaged , there was no leak of radioactivity and the vessel's hull is intact .───美国海军说，旧金山号的核反应堆没有损伤，没有放射性物质泄漏，潜艇舰体也完好无损。
They argued that only a negligible rise in atmosphere radioactivity resulted from the test.
