Представлені результати релятивістського розрахунку ймовірностей радіаційних переходів і часів життя збуджених станів для важкої рідбергівської  атомної системи в поле чорнотільного (теплового) випромінювання на прикладі рубідію. В якості теоретичного підходу ми застосовуємо комбінований релятивістський енергетичний підхід і релятивістську багаточастинкову теорію збурень з оптимізованим діраківським нульовим наближенням. Отримано розрахункові дані для ймовірностей радіаційних переходів і часів життя збуджених станів, зокрема атома рубідію в рідбергівських станах з головним квантовим числом n = 10-100. Проведено порівняння отриманих теоретичних даних щодо ефективних часів життя для групи рідбергівських nS станів атома рубідію при температурі T = 300K з експериментальними даними, а також даними альтернативного теоретичного розрахунку на основі удосконаленої квазікласичної моделі. Показано, що точність теоретичних даних забезпечується коректністю обчислення відповідних релятивістських хвильових функцій і повнотою обліку обмінно-кореляційних ефектів.
