Thanks appreciate the explanation.  I will likely buy one of your kits and get online with you.  I am in South America, and am curious about the radiation here.  I have a NukAlert key-chain dosimeter and it never goes off here.  
I see you recommend some websites about the Fuki disaster.  Have you ever heard of Jim Stone Freelance website, and if so what do you think about his theory?
I have never heard about him before now. The sources I visit often do not leave me with much free time to explore new ones. Thanks.
