초록
Methylene blue-PVA필름을 만들어 krad 영역의 선량계(線量計)로서 사용할 수 있는지를 조사하였다. 선원(線源)으로서는 X-선을 사용하였고, 일정량의 X-선을 조사(照射)한 후 methylene blue의 흡수파장(吸收波長) 670 nm 에서 분광분석계(分光分析計)로써 optical density를 측정하여 조사선량(照射線量)에 대한 optical density 곡선을 얻었다. dose-optical density 곡선은 비교적 좋은 비례성(比例性)과 합리적인 재현성(再現性)을 보였다. 따라서 본 methylene blue-PVA 계(系)는 이 선량(線量)영역의 선량계(線量計)로서 적합함을 시사해준다.
A methylene blue-PVA system has been tested as a krad range dosimeter. Mb dye films were fabricated by casting PVA in solution with the methylene blue. In the air the system was irradiated by X-ray and the decolorisation of the dye film was found to remain unchanged for sufficiently long time. The radiation response on optical density at 670 nm in the Mb-PVA system shows a quite good linearity and reproducibility in the krad range.
