Abstract
THE importance of biological solids as model substances for radiation reactions has grown considerably since the milieu-dependence of some radiation effects in solids has been demonstrated1–5. In this connexion the electron spin resonance investigation of X-irradiated keratin offers two additional advantages. First it gives a broad characteristic signal, which is probably due to a sulphur-containing radical6. Therefore it should be possible to follow a single reaction in the solid, independently of other reactions which possibly may occur. The second advantage is also based on the fact that the keratins contain a large amount of sulphur7. Therefore it seems possible to obtain some information about radiation protection mechanisms from radiation experiments on keratins.
