Radiation measurements of surface and deep organ doses were performed aboard the International Space Station, for the period of January 2006 to April 2007, using a MOSFET dosimetry system combined with the Matroshka-R spherical phantom. The averaged internal and surface dose rates are found to be 0.19 and 0.29 mGy d(-1), respectively. The levels of radiation dose to blood-forming organs (BFO) and to surface organs are compared with recommended safe limits. The maximum measured BFO dose has an average dose rate of 0.23 mGy d(-1) (84 mGy y(-1)), corresponding to 44 % of the recommended annual limit of 0.5 Sv, for a space radiation quality factor of 2.6. The annual surface dose is found to be higher at 126 mGy, corresponding to 16 % of the eye dose limit and to 11 % of the skin dose limit. Doses calculated using the Spenvis software showed deviations of up to 37 % from measurements.
2006年1月至2007年4月期间，在国际空间站上使用MOSFET剂量测定系统结合Matroshka-R球形体模进行了表面和深部器官剂量的辐射测量。发现平均内部和表面剂量率分别为0.19和0.29 mGy d⁻¹。将造血器官（BFO）和表面器官的辐射剂量水平与推荐的安全限值进行了比较。对于空间辐射品质因数为2.6的情况，测量到的最大BFO剂量的平均剂量率为0.23 mGy d⁻¹（84 mGy y⁻¹），相当于推荐年限值0.5 Sv的44%。发现年表面剂量较高，为126 mGy，相当于眼剂量限值的16%和皮肤剂量限值的11%。使用Spenvis软件计算的剂量与测量值的偏差高达37%。
