Что такое радиация?
Радиация - это энергия, выделяемая материей в форме лучей или высокоскоростных частиц. Существует много известных форм радиации.
Например, мы используем свет, тепло и микроволновые печи каждый день.
Доктора используют рентгеновские лучи, чтобы увидеть наши тела изнутри.
Телеволны и радиоволны предоставляют нам наши любимые программы.
Всё это формы радиации. Так же естественным образом радиация представлена и в окружающей среде. Солнце и звёзды посылают постоянный поток космического излучения на Землю. Также, сама Земля является источником наземного излучения. Радиоактивные материалы (в том числе уран, торий и радий) существуют в природе в почве и камне. По существу, весь воздух содержит радон, вода содержит небольшое количество растворенного урана и тория, и вся органическая материя (растения и животные) содержит радиоактивный углерод и калий. Кроме того, все люди имеют внутреннее излучение, в основном, от радиоактивного калия-40 и углерода-14 внутри их тел с самого рождения. И, наконец, люди также подвергаются воздействию излучения от ядерного топливного цикла, от транспортировки радиоактивных материалов и радиоактивных осадков, от испытаний ядерного оружия и аварий реакторов (таких как Чернобыль).

While working in France at the time of Becquerel's discovery, Polish scientist Marie Curie (was becoming/became /had become) very interested in his work. Marie and her husband, French scientist Pierre Curie (were studied/ had been studied/ studied) radioactive materials, particularly pitchblende, therefore from which uranium (was extracted/ extracted). By this time they (noticed/ were noticed/ had noticed) that pitchblende (was/ were/ had been) strangely more radioactive than the uranium extracted from it. Their work (was resulting/ resulted/ had resulted) in the identification of two new chemical elements. The first element, they named "polonium," after Marie's native country, Poland. The other element they (named/ were named) "radium," for its intense radioactivity. Radium became the initial industrial gamma ray source. The couple (was becoming/became) well known for their work, but they also became victims of radiation poisoning. When early scientists (had been working/were working/worked) with naturally occurring radioactive materials, the effects of radiation on the human body (were little understood/ little understood), or (ignored/ were ignored).
