目的探讨如何处理和回收放射性污染的一次性注射器．方法将注射过放射性核素的一次性注射器，按其放射性核素种类不同分别置于铅筒内，待自然衰变．根据放射性核素半衰期的长短．分别放置０．５、１、２、３、４个月后，用Ｇｅｎｅ－１型放射性测污仪分别测定剩余辐射剂量率．结果注射过９９ｍＴｃ的一次性注射器放置半月，而用１５３Ｓｍ、１３１Ｉ和３２Ｐ则分别需放置２、３、４个月后，测定剩余辐射剂量率达空气本底水平，可按普通的一次性注射器回收和处理．结论用放射性放置衰变方法，回收和处理放射性污染的一次性注射器是一种可行、安全的方法．
Objective To explore how to dispose of and recycle radioactively contaminated disposable syringes. Methods The disposable syringe injected with radionuclide was placed in the lead cylinder according to the type of radionuclide. According to the length of the radionuclide half-life. After being placed for 0.5, 1, 2, 3, and 4 months, respectively, the remaining radiation dose rate was measured using a Gene-1 type radioactive fouling instrument. Results One-time syringes injected with 99mTc were left for half a month, while those with 153Sm, 131I, and 32P were placed for 2, 3, and 4 months, respectively, and the remaining radiation dose rate was measured up to the air background level, which can be recovered as ordinary disposable syringes. And processing. 5. Conclusions The use of radioactive decay method to recover and dispose of disposable radioactive syringes is a feasible and safe method.
