If there's one word that
scares even the very brave, it's radiation. It conjures images of
atom bombs and Chernobyl. Nuclear power run rampant, fallout and
cancer.
Sure, these things are all
out there, but did you know you can come into contacts with
surprisingly large amounts of radiation in every day life even if
you're not a nuclear technician or a radiologist? (Let's not forget
that radiation can be beneficial as well).
That's what we're looking
at today, strange unexpected places to find radiation.
First up, it occurs
naturally in certain kinds of food, like bananas and Brazil nuts.
That's right, although both are very good for you, the roots of their
trees go so deep into the ground that they naturally absorb radiation
from the ground. Enough radiation in fact to set off security scanners in airports.
This is not our fault, it's always been like that.
But not to worry, you
can't get sick from eating either bananas or Brazil nuts, though if
your partner is allergic to nuts, the allergen from the Brazil but
can be transmitted sexually.
Speaking of naturally
occurring places to find radiation, did you know granite absorbs the
stuff terribly well? Granite like your kitchen counter top (if yours
is fancier than mine), or the Grand Central Station in New York for
example. You see, the stuff just floats about and gets trapped in the
granite where it sits happily, well, radiating. The Grand Central
Station leaks more radiation than is legally allowed for a nuclear
power plant. Food for thought.
OK, so since you're
feeling freaked out, maybe you should to sit down, have a cookie from
the old jar granny left you, scratch your cat a bit and read your
favourite glossy magazine.
Drat, you're still not
safe. And all because of irradiated clay and paint.
Kitty litter is often made
from bentonite clay, which is - you know it - radioactive.
Pottery, particularly red
pottery from before 1960, may contain surprisingly large amounts of uranium.
And do you know how they
make your magazine so glossy? By using kaolin or china clay, which
can contain both uranium and thorium. Fun!
But fear not, gentle
reader. All these radiation levels are pretty safe. Or are they?
Until next week, try not
to eat too much kitty litter!
