Echantillon de sources Gamma
{"Image DocumentName": "Echantillon de sources Gamma", "Image ImageDescription": "Sealed sources are almost always gamma sources since the characteristic of being sealed acts to shield beta and alpha radiation. Most high energy gamma emitters such as cobalt-60 and caesium-137 are also beta emitters. Encapsulating the source results in shielding the beta radiation but permitting the gamma radiation to escape.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
