The data on the cosmic radiation LET spectra at different distances from the Earth (inside and outside the magnetosphere) indicate that there is a considerable screening effect of the geomagnetic field with respect to the galactic cosmic radiation. The screening coefficient, including the screening effect of the Earth itself, is about 7 for the absorbed dose and about 26 for the dose equivalent. The galactic cosmic radiation accumulated dose equivalent outside the Earth's magnetosphere and behind a shield thickness of 1 g/cm2 is about 95 rem per year near the solar minimum. LET spectrum data for different altitudes in the near-Earth region of space can be used in the manned space flight radiation protection for spacecraft shielding calculations and for the development of dosimetric control instruments, as well as in the planning and data interpretation of radiobiological experiments in space.
关于在距地球不同距离（磁层内外）的宇宙辐射传能线密度谱的数据表明，地磁场对银河宇宙辐射有相当大的屏蔽效应。包括地球自身屏蔽效应在内的屏蔽系数，对于吸收剂量约为7，对于剂量当量约为26。在太阳活动极小期附近，地球磁层外且屏蔽厚度为1克/平方厘米后的银河宇宙辐射累积剂量当量约为每年95雷姆。近地空间区域不同高度的传能线密度谱数据可用于载人航天飞行辐射防护中的航天器屏蔽计算、剂量控制仪器的研发，以及空间放射生物学实验的规划和数据解读。
