1958 J. Jagger in Bacteriol. Rev. 22 100/1 ‘Post-UV-photoprevention’ would describe completely what is here called photoreactivation. In addition, this term would distinguish the present effect from photoprotection (‘pre-UV-photoprevention’).
1962 Photochem. & Photobiol. 1 256 Photoprotection is found to require, at an ultraviolet survival level of 2 per cent, about three times as much radiation energy as photoreactivation.
1975 Nature 17 Apr. 628/1 We..conclude that photoprotection does not contribute to the increased survival of HSV in Jay Tim cells treated with photoreactivating light.
1998 Zest July 94/1 The nice thing about clothing is that it's a definite method of photoprotection.
