In Studio: Nuclear Engineer Explains Radioactivity

Massachusetts officials announced this past weekend that rainwater in the Bay State had tested positive for small amounts of radiation.

Experts say the radioactive isotope that was found in the water originated at the badly-damaged Fukushima nuclear power plant in Japan, which nearly melted down after the earthquake and tsunami there.

URI Professor Dr. Bahram Nassersharif joined Chief Meteorologist Fred Campagna in our downtown Providence studio First @ Four and explained that the amount of radioactivity found in the water in Massachusetts is only about one-fifth as high as the radiation you'll find in an everyday banana.

Dr. Nassersharif also showed Fred that there's radiation in many things you have around the house and interact with every day, including those bananas, nuts, granite countertops, and smoke detectors – and the levels of radiation you'll find in those things is nothing to worry about.
