October 3, 2014. Presentation Overview. PFRC will produce at least 100 times fewer neutrons than a D-T burning reactor. Neutron radiation is still damaging, but PFRC will require much less shielding than a D-T Tokomak (less than a meter compared to several meters). . Muller. . counter. GM counter. construction.

This PowerPoint presentation provides an overview of how to use the LSC for qualitative purposes such as for contamination surveys. You will be provided detailed instructions on specific LSC counting methods and materials by experienced personnel in your particular lab. Proper use of the LSC is monitored by supervisor, the IRUA holder for whom you work and by Radiation Safety as a part of their audits of your radiation safety program compliance.. : . monitoring . radiation doses delivered to cancer patients.

In this unit pupils will learn about heating and thermal equilibrium: temperature difference between 2 objects leading to energy transfer from the hotter to the cooler one, through contact (conduction) or radiation; such transfers tending to reduce the temperature difference; use of insulators. .
