纽约市居民每日摄入的U、Th和Ac系列的长寿α放射性成员已通过对饮食、水和空气样本的测量进行了估计。以mBq计，从吸入、食物和水摄入的每日总摄入量分别为18（234U）、0.7（235U）、16（238U）、6（230Th）、4（232Th）和52（226Ra）。由此推断，228Th和228Ra的日总摄入量分别为4和35mBq。
The daily intake of long-lived alpha-emitting members of the U, Th and Ac series by New York City residents has been estimated from measurements of diet, water and air samples. The total daily intakes from inhalation, food and water consumption in mBq are 18 (234U), 0.7 (235U), 16 (238U), 6 (230Th), 4 (232Th) and 52 (226Ra). From this, we infer that the total daily intakes of 228Th and 228Ra are 4 and 35 mBq, respectively.
