Media Advisory: Radiation Expert Offers Answers to Three Common Questions

Georgetown University Medical Center’s Timothy Jorgensen can help provide answers for your readers/viewers/listeners. Here is some guidance regarding the current situation (9am ET, 3/14/11):

1) Hydrogen explosions are not nuclear explosions. Hydrogen turns to water when an explosion happens. The main issue with the hydrogen explosions is if the blast damages a container holding nuclear material.
2) If a meltdown were to occur, radiation is not likely to reach the West Coast. Factors impacting that include the amount of radiation released, how high into the atmosphere it travels and weather conditions.
3) Jorgensen also points out that if damage occurs to the containers, there won’t be a bomb-like explosion of the nuclear material, but rather a leakage.

Timothy Jorgensen, PhD, MPH is chair of the radiation safety committee at GUMC and a member on the National Council on Radiation Protection. He has a PhD in environmental health and holds a certificate in risk science.  He is a molecular radiation biologist interested in risk assessment of environmentally-induced human cancer, from both chemicals and radiation. Jorgensen is an associate professor in the Department of Radiation Medicine at Georgetown University Medical Center and is a member of the Georgetown Lombardi Comprehensive Cancer Center
