Nuclear science event hosted at Illinois Tech
American Nuclear Society member Jeff Terry hosted this year’s Nuclear Science Week meeting at the Illinois Institute of Technology (Illinois Tech) on October 26. In his opening remarks, Terry, a physics professor at Illinois Tech, described the institute’s 12-year history of Nuclear Science Week events, going back to the 2012 meeting that included the Nuclear Clean Energy Indy car on display.

Shielding | Special Issue on the 11th International Conference on Radiation Shielding and the 15th Topical Meeting of the Radiation Protection and Shielding Division (Part 2) / Radiation Protection | doi.org/10.13182/NT09-A9226

A shielding layout for a 40-MeV electron linac is presented. The linac building consists of 15-cm concrete roof and walls, and 2-m-thick shielding walls for horizontal shielding. No shielding roof covers the linac, which reduces the capital cost of the facility building. Though the present shielding layout allows an operation of up to 11.8-W averaged beam power, experimental dose equivalent rates are found to be much greater than that predicted by the skyshine formula. Monte Carlo (MCNP 4C) simulations indicate considerable contributions of radiation scattering by the thin roof and walls.
