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

The following joke is from Elinor again.
Three rotten old Grandmas were sitting on a bench outside a nursing home when a Grandpa walked by. And one of the Grandmas yelled out, 'We bet we can tell exactly how old you are.' The old man said, 'There is no way you can guess it, you old fools.' One of the old Grandmas said, 'Sure we can! Just drop your pants and under shorts and we can tell your exact age..' Embarrassed just a little, but anxious to prove they couldn't do it, he dropped his drawers. The Grandmas asked him to first turn around a couple of times and to jump up and down several times. Then they all piped up and said, 'You're 87 years old!' Standing with his pants down around his ankles, the old gent asked, 'How in the world did you guess?' Slapping their knees and grinning from ear to ear, the three old ladies happily yelled in unison - - 'We were at your birthday party yesterday!'
