Our current research is in the area of environmental impacts of radiation.  The main focus recently has been 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 (he Radiation Protection and Measurement Program at CSU has been collaborating with Fukushima University’s Institute for Environmental Radioactivity (http://www.ier.fukushima-u.ac.jp/web/a_overview_e.html). We typically send students each summer to perform field research in the Fukushima Exclusion Zone.  Students have also collaborated or visited Hiroshima University (http://phoenixprogramlp.hiroshima-u.ac.jp/en/) and given presentations in association with the Phoenix program.

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