on-site. Over the years, the water has been treated to remove most radioactive contaminants, leaving only tritium — a radioactive isotope of hydrogen — present at low levels. Get the latest from UCA News. Sign-up to receive our daily...

선생님, radiation도 radioactive도 둘다 방사선으로 해석되는데, 뒤에 예를 들면 radioactive iodine, radioactive isotope 이렇게 radioactive 뒤에 꾸며주어야 하는 단어가 있으면 radioactive 그냥 혼자 방사선의 뜻으로만 쓰일때는 radiation 으로...

lacking its imaginary explosive properties). These include the most likely candidate, lithium-6 deuteride, a radioactive isotope of lithium hydride that is used as a fuel in a specific design of nuclear warheads. Various other chemicals...

원소는 탄소-12와 탄소-13처럼 안정적이며 변하지 않는다. 그러나 탄소-14는 불안정한 핵을 가지고 있는 방사성 동위원소(radioactive isotope)다. 방사성 동위원소는 양성자, 중성자 또는 둘 다의 수가 변하는 원소를 의미한다. 이러한 변화를 방사성...

water have been pumped out of the damaged reactor buildings every day. Most of the radioactive isotopes have been removed using a complex filtration process. But one isotope, tritium, cannot be removed so the water has been stored in a...
