Yo, brothers and sisters. I'm the new kid on the block, so I don't know if this is the correct mode of introduction. So, "Me - Sky-High, You - ?"
Brother Fraser told me to ask this question here and to wait quietly for enlightment. So, check this out: there has to be more than one satellite up there monitoring Earth radio-activity, for decades now. The other side nuclear tests had to be monitored and recently after enough radioactive material to build 5 A bombs Hiroshima class is unacounted for, the need got greater. Now probably the real performant birds are military and therefore out of this world and forbiden to you. lousy civilian !

Still I wonder if there wouldn't be a purely scientific non-military contaminated one that could see for instance if there is a big leak in a nuclear power plant, or from a radioactive residue deposit. Now, given the fact that it took the Goverment 25 years to acknoledge that there was real contamination for the soldiers exposed to radiation during military nuclear tests back in the 50-es, and that it takes only a few minutes of personal exposure to pile the **** higher than you can manage, I would be vastly interested to know if such info is available and how.
If this is not the proper introuction, sorry for the breach in protocol, and please feel free to ask questions, should you have any. First of all, I would GREATLY appreciate some answers.
Regards, and may your day be the one ! when Sky-High dreams come true...
