TY - JOUR AU - Tran Van Hung PY - 2019/01/06 Y2 - 2024/03/29 TI - Effective doses for external exposure from the photon radiation field of soil contamination JF - Science & Technology Development Journal: Natural Sciences JA - STDJNS VL - 2 IS - 1 SE - Original Research DO - https://doi.org/10.32508/stdjns.v2i1.679 UR - http://stdjns.scienceandtechnology.com.vn/index.php/stdjns/article/view/679 AB - Organ and effective doses of adult for external exposure to photons uniformly distributed in soil were calculated using a MIRD-5 type phantom and MCNP code. The calculations were performed for mono-energic photon sources with source energies from 0.01 MeV to 5 MeV. The effective dose coefficients in this calculation using MCNP code were compared to the calculated results in report of Keith F. Eckerman vĂ  Jeffrey C. Ryman. ER -
