Evaluating bone marrow dosimetry with the addition of bone marrow structures to the medical internal radiation dose phantom

نویسندگان

چکیده

Background Reliable estimates of radiation dose to bone marrow are critical understanding the risk radiation-induced cancers. Although medical internal phantom is routinely used for estimation, not defined in phantom. Consequently, methods indirectly estimating have been implemented based on surrogate volumes or average soft tissue. Methods In this study, new structures were and evaluated Geant4, offering improved fidelity. The equivalent was calculated across medical, occupational, space exposure scenarios, compared with results using prior indirect estimation methods. Conclusion Our show that may be overestimated by up a factor three when traditional fidelity method, specifically at clinical x-ray energies.
