ASTM E1855 Dosimetry for Low-Energy X-Rays
The ASTM E1855 standard provides a method for determining absorbed dose in low-energy x-ray beams, specifically targeting applications where the energy of the x-rays is below 30 keV. This service is crucial for ensuring accurate dosimetry and compliance with international standards in industries such as nuclear medicine, radiography, and industrial radiography.
Low-energy x-rays are often used in medical diagnostics, particularly in fluoroscopy systems that utilize low kV X-ray generators like those found in dental offices. In these settings, precise dose measurement is essential for patient safety and regulatory compliance. ASTM E1855 specifies a dosimetry system designed to account for the unique properties of x-rays at lower energies, which can behave differently than higher-energy beams.
One key aspect of this service involves the selection and use of appropriate dosimeters tailored for low-energy x-ray environments. The standard recommends the use of thermoluminescent dosimeters (TLDs), optical stimulated luminescence dosimeters (OSLDs), or other suitable devices that can accurately measure absorbed dose in these specific conditions.
The ASTM E1855 method involves placing a calibrated dosimeter in proximity to the x-ray source and then measuring the emitted radiation. The dosimeter is then removed from the field, processed according to specified procedures, and read on a thermoluminescence reader or other appropriate equipment. Reporting typically includes the absorbed dose measured, any relevant calibration factors, and adherence to the standard.
For industries using low-energy x-rays, this service ensures that all measurements are accurate and traceable to international standards. This is particularly important for quality assurance in radiography processes where precise dosimetry can affect image quality and patient safety.
