X-ray fluorescence (XRF) is a non-destructive analytical technique used to determine the chemical composition of materials. It is used extensively in the metal manufacturing, inspection and recycling industry. You might use it to identify the metal and alloys in a scrapyard, verify the content of your raw materials in your manufacturing plant, or check the gold content in a piece of jewelry.
Is Handheld XRF Safe?
The answer is YES.
When it is used properly.
Because this fluorescence is unique to the elemental composition of the sample, XRF is an excellent technology for qualitative and quantitative analysis of the material composition. While the radiation emitted from a portable XRF analyzer is similar to the exposure received in a normal medical or dental x-ray, care must be taken to always point a handheld XRF analyzer directly at the sample and never at a person or a body part.
Primary Radiation – Radiation that originates from the sealed source or x-ray tube directly and has not interacted with a sample
Secondary Radiation – Radiation that has scattered off of or was induced within the sample or other components of the analyzer.
XRF happens when a fluorescent (or secondary) x-ray is emitted from a sample that is being excited by a primary x-ray source. There are three factors will help minimize your radiation exposure: time, distance, and shielding. While the radiation emitted from a portable or handheld XRF elemental analyzer is similar to the exposure received in a normal medical or dental X-ray, care must be taken to always point a handheld XRF analyzer directly at the sample and never at a person or a body part.
Tips to Use the XRF Safely During Analysis
Avoid place a part of their body in the primary beam path.
Point away from any persons within 15 feet (4.57 m)
Use appropriate optional accessory like test stand as part of the package
Provide radiation safety training to operators
Never hold samples during analysis
Be aware of primary beam indicator lights
Handle and use with respect
Store securely – obey local storage requirements
Test Stand and Shield
