Ответ:

По степени радиационной опасности с точки зрения потенциальной тяжести последствий внутреннего облучения радионуклиды разделены на группы радиационной опасности. В порядке убывания радиационной опасности выделены 4 группы с индексами А, Б, В и Г.

В малых дозах радиационное излучение может стать катализатором процессов, приводящих к раку или генетическим нарушениям, а в больших дозах часто приводит к полной или частичной гибели организма вследствие разрушения клеток тканей.

Результатом облучения являются физико-химические и биологические изменения в организмах.
