Ionising radiation primary beam risks
Webhealth. This radiation emitted from the XRF can be separated into 2 types: primary radiation and secondary radiation. Primary radiation is radiation that is produced by the analyser and emitted through the window aperture. Individuals should never place any part of their body in the primary beam when the x-ray tube is on. WebExposure to such intense radiation can cause severe injury to the skin, the underlying bone, or the eye in a short time (e.g. seconds). 3.3 Injury resulting from exposure to a primary beam may not be immediately apparent. It may take a few hours or several days before the extent of the injury may be assessed accurately. 4. Responsibilities
