При уровнях активности радионуклидов меньше приведенных в таблице и условии применения МЗУА и МЗА одновременно, 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:
3
А - 1 x 10 Бк;
4 5
Б - 1 x 10 и 1 x 10 Бк;
6 7
В - 1 x 10 и 1 x 10 Бк;
8 9
Г - 1 x 10 и 1 x 10 Бк, а также Kr-83m, Kr-85m и Xe-135m.
