Measurements have been made of the gastrointestinal absorption in humans of 239Np and 242Cm administered together in citrate media. Using five volunteers, consistent results of (2.0 +/- 0.2) x 10(-4) and (1.7 +/- 0.3) x 10(-4) were obtained for Np and Cm respectively; the quoted uncertainties are the standard errors of the means. A progress report is given of work to measure the f1 value for Pu in humans. Early work suggests an f1 value of 2 x 10(-4).
已对在柠檬酸盐介质中共同给予人体的239Np和242Cm的胃肠道吸收情况进行了测量。使用5名志愿者，分别获得了Np和Cm的一致结果，即(2.0±0.2)×10⁻⁴和(1.7±0.3)×10⁻⁴；所引用的不确定度为均值的标准误差。给出了测量人体中钚的f1值的工作进展报告。早期工作表明f1值为2×10⁻⁴。
