NIHPublication No 055286March 2005The radiation beam in interventional fluoroscopy procedures is typically directed at a relatively smallpatch of skin for a substantial length of time Thisarea of sk. Applications. Artificially produced radioisotopes find many uses in agriculture, industry, medicine, forensic science, and scientific research..
