Hope nobody drank the rainwater here in March

Nope. He's correct. A rad is a unit of absorbed radiation dose. It also has a metric equivalent, the gray. 100 rads = 1 gray

Different methods are used to remove different elements. ONE method is reverse osmosis but it is not the only method nor is it typically a method that is used on its own. Treating the water at Fukushima right now involves 4 different companies doing multiple things in series. One of those steps is indeed revers osmosis but not before the cesium and iodine are removed through other methods.

Here's a little article on using rads, rems, beq, etc...

And rad (as in radian) is used to measure angles. I had never heard of rad in terms of absorbed radiation, but it looks like you are correct too.

Rads are for measuring coolness level.

It'll take more than a poor article by a biased author to convince me that actually happened.

So you are saying that Mr Pellerin, Chief of Health Canada's radiation-surveillance division is wrong, or was mis-quoted?

“It’s above the recommended level [for drinking water],” Eric Pellerin, chief of Health Canada’s radiation-surveillance division, admitted in a phone interview from Ottawa. “At any time you sample it, it should not exceed the guideline.”

Oh yeah and we shouldn't compare rain water with drinking water. One comes from the sky and the other comes from the tap. Thanks for your help.

No you shouldn't because one falls from the sky and at the very least is diluted by a huge degree before it comes out your tap. Now if tap water were sampled you might have concern (though remember advisable levels are typically at levels well below what is dangerous).

I'm saying the author of the article is (intentionally it would appear) comparing things that aren't the same in order to try and get the reader to draw a spurious conclusion.

If you have an actual argument to make, then make it and support it. Otherwise why should anyone pay attention to what your are trying to say?

this is why we should only drink bottled water.

8.18 becquerels = 0.54 BED (Banana Equivalent Dose), which doesn't sound so bad. On the other hand, if it was raining bananas, I sure as hell would be heading into my fallout shelter.

I keep hoping to be able to deadpan on CP, and it never works.

I think it's pretty rad.

Mr Pellerin likely wasn't wrong, nor mis quoted. It's likely true that the rainfall measured at a level twice the regulated standard for tap water. However, this is of essentially no concern to us. That's why no one is worried. Even if it was a phenomenon that carried on permanently, it wouldn't really be a concern.

I would certainly think that rainwater could often contain more radiation than tap water would.
