  •  By your own numbers we have tripled (0+ / 0-)

    our natural radiation exposure.

    •  Huh? (0+ / 0-)

      2000 + 3.9 = 2003.9

      which is not three times the value of 2000 pCi/liter from just one naturally occurring radioisotope.  You mean that we have increased out natural radiation exposure by about 0.2%.

      Math is not your strong point, is it?

        •  Sigh ... (0+ / 0-)

          It's called units. Numbers for physical quantities are worthless without them. You might want to try reading a sixth-grade science textbook, which would explain how they work.

          The figure that you cite for the specific activity of potassium-40 in milk is 1.5 pCi per gram. The article that you linked to earlier expressed specific activity in units of pCi per liter.

          Since the density of milk is about 1.03 g/cc, a simple unit conversion reveals that

          (1.5 pCi/g) × (1.03 g/cc) × (1000 cc/liter) = 1545 pCi/liter

          Rounded to one significant digit (which is all that is needed in this example), that's 2000 pCi/liter.

          I have yet to meet an anti-nuke who can do even the most basic of scientific calculations, and here is yet more evidence of what I'm talking about.

          •  You're right (0+ / 0-)

            But how does the gloating and condescension help your cause?

            •  Well, how does ... (1+ / 0-)

              pointless fearmongering and making amateurish mistakes help your cause?

              My initial reply was polite enough. However, the more you kept insisting, incorrectly, that I was wrong, the more I lost my patience.

              This being a public forum, I'm not correcting you for your benefit. By pointing out your mistakes and emphasizing how very basic they are, I hope that those reading this will take away an important message from this exchange, so that the next time they run across some sort of idiotic, fearmongering claim on the Internet, they won't automatically take it at face value. I want them to question such claims with a bit of critical thought, and I want them to apply some context so that they understand, not just react.

              •  Nicely put (0+ / 0-)

                I'm going to quote from this comment liberally.

                Causation was, is, and ever shall be a slippery bitch, so we're best sticking with noting the facts
