A radiation expert can reconstruct the source, radiation type and energy, duration of exposure, distance or geometry, shielding, monitoring data, detector response, and available dosimetry. The review may also address whether instruments were appropriate and calibrated and whether the reported dose can be reproduced from the available evidence. NRC identifies time, distance, and shielding as fundamental radiation-protection concepts, while NIST maintains national standards for ionizing-radiation measurements and dosimetry.
The technical review may involve X-ray, CT, fluoroscopy, nuclear medicine, or other ionizing-radiation exposures, depending on the assignment. Relevant evidence can include examination protocols, equipment settings, dose indices, dose reports, calibration and quality-assurance records, and cumulative exposure information. FDA notes that radiography, CT, and fluoroscopy use ionizing radiation and that dose optimization should produce adequate clinical information while minimizing unnecessary exposure. Whether a particular examination should have been ordered or how an image should have been interpreted may instead require a radiologist or another appropriate physician.
Radiation expertise is primarily concerned with radiation generation, measurement, dose, exposure, shielding, instrumentation, and protection. Diagnostic radiology focuses on the medical use and interpretation of imaging studies. For example, a technical radiation expert may analyze the dose associated with a chest X-ray, while a radiologist is generally better positioned to address whether the image showed an abnormality and how it should have been interpreted. FDA distinguishes the radiation-safety and dose aspects of medical X-ray imaging from the diagnostic clinical purpose of the examination.
Ionizing radiation can increase cancer risk, but the magnitude of risk depends on factors including dose, dose rate, age at exposure, organs exposed, and other circumstances. CDC states that radiation effects depend strongly on dose and that sufficiently high ionizing-radiation exposures can cause cancer later in life. Estimating population-level radiation risk is different from determining the cause of an individual cancer. NCI's RadRAT, for example, estimates lifetime cancer risks using organ-specific doses and demographic inputs and reports uncertainty ranges. A case involving whether radiation caused a particular cancer may therefore require radiation-dose expertise together with Oncology, epidemiology, or other disease-specific expertise.

Radiation Oncology is the medical specialty concerned with using ionizing radiation to treat cancer and certain other conditions. A radiation oncologist may be appropriate when the dispute involves treatment selection, target definition, radiation-therapy planning, clinical dose prescription, treatment delivery, toxicity, or oncology follow-up. The American Board of Radiology describes radiation oncologists as physicians who use ionizing radiation to treat cancer and other conditions. General Radiation expertise is more directly suited to technical questions involving exposure, dose reconstruction, measurement, shielding, sources, instrumentation, or radiation protection.
