Radiation sterilization - hoshasenmekin (English spelling) radiation sterilization
Radiation has a germicidal effect, and the process that actively utilizes this effect is called radiation sterilization.
[Sterilization of medical equipment]
Radiation sterilization of medical equipment is a process that is currently in widespread use worldwide. In recent years, many disposable plastic medical equipment that is sensitive to heat has come into use, and a process is being used to sterilize these by irradiating them with 2 to 3 Mrad of gamma rays from cobalt-60. Traditionally, gas sterilization using ethylene oxide was used, but this method is problematic in terms of ease of operation and adverse effects caused by residual adsorption of gas. In response to these problems, radiation sterilization is gradually replacing this method, as it allows products to be easily sterilized after packaging and can be applied to objects that are structurally difficult to sterilize with gas.

放射線は殺菌効果を有しており,これを積極的に利用するプロセスを放射線滅菌と呼んでいる。
[医療用具の滅菌]
 現在世界的に広く実用に供されているプロセスに医療用具の放射線滅菌がある。近年プラスチック製ディスポーザブルタイプの熱に弱い医療用具が数多く使用されるようになっているが,これにコバルト60からのγ線を2~3Mrad程度照射して滅菌するプロセスが利用されている。従来はエチレンオキシドによるガス滅菌が行われてきたが,操作が簡便でなく,ガスの吸着残留による悪影響などに問題があり,それに対し製品をパックした後簡単に滅菌できることや,構造上ガス滅菌が困難な対象物にも適用可能であるといった特徴のため,しだいに放射線滅菌に置き換えられつつある。
