| description | This article focuses on the in-situ calibration of area radiation monitors by
examining changes in backscatter factors. A mobile X-ray irradiation device
was developed, and a reference radiation level was established. Using the
Monte Carlo method, an in-situ calibration measurement model was created
to study backscatter factors at different distances and radiation field
conditions for radiation qualities ranging from N-60~N-200. The accuracy of
the simulation was verified, with a relative deviation between simulation
and experimental results not exceeding ±4.7 %. In addition, the variation
of the backscatter factors with different chamber-wall distances and wall
materials was simulated. Results indicate that backscatter factors for all
materials decrease as the chamber-wall distance increases. For conventional
concrete, the maximum backscatter factor within the studied energy range did
not exceed 1.35. It is important to note that for heavy concrete and lead,
the presence of K absorption edges can result in a sudden increase in
scattered radiation. |
