Our current research is in the area of environmental impacts of radiation, focusing on environmental modeling, examination of the impact of the 2011 Fukushima accident, and uranium mining.

Since 2013, the Radiation Protection and Measurement Program at CSU has been collaborating with Fukushima University’s Institute for Environmental Radioactivity.

Students have the opportunity to spend summers performing field research in the Fukushima Exclusion Zone. Students may also participate in Hiroshima University's Phoenix Leader Education Program for Renaissance from Radiation Disaster program. 

Students typically spend a week at Los Alamos National Laboratory, and attend multiple "field trips" to various sites across the west.
