I’ve been reading archived newspapers from 1979, a time in my life when I didn’t pay too much attention to world events. Now that I’m doing my bit for recorded history, I enjoy reminding myself, or educating myself, on vaguely remembered moments from the years I actually lived through. I came across a piece in the New York Times, that had Senator John Glenn being shown the facade of a Washington building, and told by his guide that there was more radiation emanated by the granite than was detectable in the air around Three Mile Island (the accident occurred March 28, 1979).
That made me curious about my favorite garden rock, above. I learned, doing a little research, that pink and red granites give off more than greys and blacks—a combination of radon gas and gamma rays, chiefly. Unfortunately, a Geiger counter won’t detect levels in granite reliably, if at all, due to ordinary background radiation in the environment. And the other machines, for non-professionals, are too expensive to buy. So I guess I’ll never know how powerful my pink rock is.
(If you have granite countertops, don’t worry. Here is a PDF from the Health Physics Society explaining more.)
Above, a thing you don’t see often, since birds of prey don’t walk on the ground. But they do rocket down from the treetops onto passing squirrels and rabbits. At night, I seem to have a lot of owl activity around my ground feeder as well, to judge by the number of pellets I find. I don’t know what comes out, whether it’s mice or flying squirrels…but whatever they are, they aren’t very wary. The owls seem to be picking them off constantly.
And finally, a super sunset from November 13.
