При уровнях активности, меньше приведенных в таблице, эффективная индивидуальная годовая доза облучения лиц из персонала и населения не превысит 10 мкЗв и в аварийных случаях 1 мЗв, а коллективная эффективная доза - 1 чел.-Зв при любых условиях использования. Эквивалентная доза на кожу не превысит 50 мЗв/год.
Природные радионуклиды оценивались при их попадании в потребительские товары из техногенных источников (например, Ra-226, Ро-210) или по их химической токсичности (для тория, урана и др.).
Если присутствует несколько нуклидов, то сумма отношений активности к их табличным значениям не должна превышать единицу. Приведенные в таблице радионуклиды в зависимости от минимально значимой суммарной активности (МЗА) делятся на 4 группы радиационной опасности:
А - 1 х 10(3) Бк;
Б - 1 х 10(4) и 1 х 10(5) Бк;
В - 1 х 10(6) и 1 х 10(7) Бк;
Г - 1 х 10(8) и 1 х 10(9) Бк; а также Кr-83m, Kr-85m, и Хе-135m.
