Froggy like robot
interesting anecdote from a chernobyl tour:
organic materials and soil may be much better at picking up ambient radiation than petroleum products and cement.[The meter was] reading 0.139 Roentgens, and by the time we picked it up out of the grass, it had gone up to .2, and was climbing. Its still nowhere near being lethal, but put it this way, you wouldnt want to stretch out on the grass for the afternoon. The grass is deadly around here, the asphalt was fine however! It doesnt absorb radiation like the soil did.
