In order to allay pains or make them cease, fifteen patients with extended tumors and generalized formation of skeleton metastases were submitted in 1976 to an internal palliative radiotherapy. They received between 0.8 and 2.7 mCi of Sr-89, five patients were treated again after four to five months because the pains had reappeared. The results were relatively good. Two patients showed a prompt effect and were completely free of pains within 48 hours, three patients did not present any demonstrable effect. The analgetic effect remained from four days to four months. Due to the utilization of the pure beta emitter Sr-89, the radiation doses measured in the patients after the application are relatively small: after the application they amount at most to 0.5 mR/h in a distance of 1 m.
为了减轻疼痛或使其停止，1976年对15例患有广泛性肿瘤并伴有全身骨骼转移瘤形成的患者进行了内照射姑息性放疗。他们接受了0.8至2.7毫居里的锶-89，有5例患者在四到五个月后因疼痛再次出现而接受了再次治疗。结果相对较好。2例患者迅速起效，在48小时内完全无痛，3例患者未显示出任何明显效果。止痛效果持续了四天至四个月。由于使用了纯β发射体锶-89，应用后在患者身上测得的辐射剂量相对较小：应用后在1米距离处最多为0.5毫伦琴/小时。
