液体放射源样品瓶的破损或漏液,会给工作台面和铅室等带来污染,造成计数不稳,本底计数过高,一经发现应及时清洗,以减少对人体的危害。 目前常用的清洗方法是首先用摄子把挤碎的玻璃渣取出来,然后用于棉球把散液吸干,最后再用酒精棉一点一点地顺方向局部擦洗,从湿到乾,反复数次,直至干净为止。应注意的是不要用水擦洗,否则会使污染面积扩大,引起金属物生锈,对仪器工作不利。
Damage or leakage of liquid radioactive source vials can cause contamination to the work surface and the lead chamber, resulting in unstable counts. The background count is too high. Once found, it should be cleaned in time to reduce the harm to the human body. At present, the common cleaning method is first to remove the crushed glass residue with a photo, and then to dry the bulk liquid with a cotton ball. Finally, the alcohol is partially scrubbed in the direction of the cotton wet, Repeat several times until it is clean. It should be noted that do not scrub with water, otherwise it will enlarge the area of pollution, causing metal rust, adverse work on the instrument.
