For simulating space environmental radiation a 2×1.7 MV tandem accelerator was used. GaAs/Ge solar cells were irradiated using 2 MeV C ions with the fluence from 3.1×109 to 6.9×1012 cm-2. Both I-V characteristics and spectral response were measured before and after irradiation.
For simulating space environmental radiation a 2×1.7 MV tandem accelerator was used. GaAs solar cells with and without MQW were irradiated using 2 MeV protons with fluences of 1×109—2×1013 cm-2, and the I-V char- acteristics and the spectral response of GaAs solar cells were measured.
Beijing Nuclear Instrument Factory (abbreviated to be BNIF) mainly deals with nuclear instrumentation used in nuclear power plants，environmental radioactivity monitoring，medical treatment，physical experimentation，and nuclear detectors.
As the total circumstance radiation which falls on the target being taken as the equivalent radiation of a blackbody at temperature To, the effect of environment radiation change on the sensibility equation of thermal imaging system is studied, and consequently the ratio emissivity ε of the target can be determined theoretically through the change of environment radiation.
Real-time monitor to solar radiation in Suzhou area is proceeded by using PC-2A type circumstance radiation monitoring instrument,Varied regularity on solar radiation、temperature、humidity is concluded by analyzing test data,and necessary data reference is provided for design and operation on solar heat utilization.
It is shown that instruments based on this principle provide environmental radiation monitoring, including monitoring of radon, thoron, and their products.
Overall, the ecological success of macroalgae in the eulittoral and upper sublittoral is supported by an enhanced oxygen-reactive scavenging system, allowing fast acclimation to the changes in environmental radiation conditions.
The measuring technique allows glass dosimeters to be applied even at doses corresponding to the environmental radiation incidence per month.
Resolving the LET spectrum of environmental radiation in space for assessing dose equivalents creates special problems due to superposition effects.
