A radioactive source shielded by 16-30 inches ot' concrete. emits 65 billion gamma rays per second and has a penetration power similiar to 1.8 grams of radium which sells for about $20,000 per gram. An equivalent amount of con- ventional X—ray equipment might cost as much as $100,000, Dr. Richard C. Jilumphreys, assistant chairman of the Foundation’s physics department, explained. “With this source, we can de~ tect hidden flaws in metal cast- ings, welds, soldered joints, and also study crystals sensitive to radiation,” Dr. Humphreys said. When not in use, the source is lowered by remote control into a grease pit which contains a lead safe with six—inch walls. In op— eration, the source is viewed with a periscope from behind a pro- tective wall.
