Q: Do radioactivity, radiation and radioactive material have the same meaning in the following sentences?
Thanks. Tiny amounts of radioactivity from Fukushima have now traveled at least halfway across the world, as far as America's East coast. We caught up with the health director in Maryland, where radiation from Fukushima was detected in the air and rainwater. When radioactive material gets into the atmosphere and can travel around into the weather patterns, it gets diluted as it goes along.

Hi Lily,
Thanks a lot! I thought they were the same. After checking over the information on the internet, I finally realize they are different. What Is Radioactivity? What is Radiation? http://chemistry.about.com/od/chemistryfaqs/f/radioactivity.htm Radioactivity, radiation and radioactive material http://www.jodblockade.de/index.php?id=23&L=1
