论文摘要
对于诊所和研究中使用的高度穿透光子和颗粒梁的标准剂量学方案存在。但是，这些方案不能直接应用于浅渗透MEV-RANGE离子束。放射学研究加速器设施已经使用了近50年的时间，以基于组织等效电离室的自发剂量测定法来照射细胞单层。 为了更好地与国际接受的标准保持一致，我们使用TRS-398建议计算出的辐射质量校正因子来描述实施一个商业，可接触的，充气的电离室，以测量低能离子的吸收剂量，以测量低能离子的水。所报告的剂量不取决于10-150 keV/micron范围内的电离密度。
Standard dosimetry protocols exist for highly penetrating photon and particle beams used in the clinic and in research. However, these protocols cannot be directly applied to shallow penetration MeV-range ion beams. The Radiological Research Accelerator Facility has been using such beams for almost 50 years to irradiate cell monolayers, using self-developed dosimetry, based on tissue equivalent ionization chambers. To better align with the internationally accepted standards, we describe implementation of a commercial, NIST-traceable, air-filled ionization chamber for measurement of absorbed dose to water from low energy ions, using radiation quality correction factors calculated using TRS-398 recommendations. The reported dose does not depend on the ionization density in the range of 10-150 keV/micron.
