Significant absorbed dose levels exceeding 1.0 Gy day-1 have been measured on the external surface of the Cosmos 1887 biosatellite as functions of depth in stacks of thin thermoluminescent detectors (TLDs) of U.S.S.R. and U.S.A. manufacture. The dose was found to decrease rapidly with increasing absorber thickness, thereby indicating the presence of intensive fluxes of low-energy particles. Comparison between the U.S.S.R. and U.S.A. results and calculations based on the Vette Model environment are in satisfactory agreement. The major contribution to the dose under thin shielding thickness is shown to be from electrons. The fraction of the dose due to protons and heavier charged particles increases with shielding thickness.
在苏联和美国制造的薄热释光探测器（TLD）叠层中，已测量到宇宙1887号生物卫星外表面超过1.0 Gy天⁻¹的显著吸收剂量水平，该剂量是作为探测器深度的函数。发现剂量随吸收体厚度增加而迅速降低，从而表明存在低能粒子的强通量。苏联和美国的结果与基于维特模型环境的计算结果之间的比较令人满意。结果表明，在薄屏蔽厚度下，剂量的主要贡献来自电子。质子和重带电粒子造成的剂量比例随屏蔽厚度增加。
