Radiation dose measurements suggest that patients undergoing extensive neuroradiological investigations may receive a corneal dose in excess of 60 rads in tissue over a relatively short period. — There is no direct evidence that lens damage occurs in man at this level but it is important that high dose levels should be appreciated and measures taken to reduce them. Protective spectacles have been devised to effect such a reduction in two high...
