The possibilities and limitations of hardening silicon semiconductor devices to the high neutron and gamma radiation levels (greater than 1016 neutrons/cm 2 (i Mev eq.) and greater than 108 rads (Si) required for the NERVA nuclear engine development are discussed. A comparison is made of the high dose neutron and garmna hardening potential of bipolar, metal insulator semiconductor (MIS), and ju...
Background: Annual patient effective dose equivalent can be considered as a quantitative physical parameter describing the activities performed in each nuclear medicine department. Annual staff dose equivalent could be also considered as a parameter describing the amount of radiation risk for performing the activities. We calculated the staff to patient dose equivalent ratio to be used as a phy...
