| 内容記述 | We suggest a practical application of particle linear energy transfer (LET)- and charge (Z)-weighted quality factors, based on the track structure model such as QNASA, for LET-based radiation dosimetry in space. Z contribution factors varying with the galactic cosmic rays (GCRs) was evaluated based on the Monte Carlo calculation to derive LET- and Z-weighted quality factors (Q*). The Q* values under solar minimum conditions in free space differs by only a few percent from values obtained with spacecraft shielding or during the solar maximum spectrum. The contribution of GCR heavy components under Q* is approximately 9% smaller compared to QICRP of ICRP-60. While this variation is not substantially large considering ambiguities in dose evaluation in space, the Q* approach provides practical dose evaluation using LET measurements. | |||||||||
