Health care workers who inspect radiation protection garments will be the primary users of a proposed ASTM International standard, ASTM WK15823 - Practice for the Fluoroscopic Inspection of Radiation Protection Garments.
"Besides visual inspection for obvious damage, garments are often inspected fluoroscopically to detect defects that are not visible to the naked eye," said Gary Glenn, Subcommittee F23.70 chair and president, Golden Gate Medical Supplies.
"Such inspections are routinely carried out without reference to a specific method and without acceptance or rejection criteria."
Glenn also said that the person performing the inspections is exposed to radiation during the inspection.
"Needless rejection of garments that could be considered acceptable is expensive and exposes the inspector to additional radiation during inspection of replacement garments," said Glenn.
In addition to inspectors, ASTM WK15823 will be useful to managers responsible for inspection programs and radiation safety officers who are responsible for overall safety within a facility, according to ASTM International.
According to Glenn, ASTM WK15823 is an extension of ASTM F 2547 - Test Method for Determining the Attenuation Properties in a Primary X-ray Beam of Materials Used to Protect Against Radiation Generated During the Use of X-ray Equipment, which was approved in 2006.
That standard defines a test method to determine the attenuation characteristics of the materials that are used in radiation protection apparel and products while the proposed standard extends to the inspection of products.
The proposed practice is being developed by Subcommittee F23.70 on Radiological Hazards, which is part of ASTM International Committee F23 on Protective Clothing.
