Government Under Fire as Radiation Is Found in Milk, Rain

I am not chemistry/nuclear professional, but it doesn't take a scientist to figure out that much. How much radiation can make it all the way across the Pacific Ocean?
There are more natural occurring radiation than what's reported in that article. Light is a form of radiation too. Fear the sun! Fear your lamp! fear your computer! fear your cell phone! They are sources of radiation too!

Ionizing and non-ionizing radiation. It makes a big difference.
It also depends a lot what is the particle of that radiation, photons, electrons and neutrons have very different effects.
