About This Product
Industrial radiography uses gamma rays from a sealed radioactive source, such as iridium-192 or selenium-75, to produce an image of the inside of a weld or casting on film or a detector. The half-life shows how quickly the source activity falls, so sources are replaced when the activity becomes too low for practical exposure times. The maximum surface dose rate is a key figure for radiation safety. This topic is taught in NDT courses, and use of such devices needs trained staff following radiation safety rules.
