Japan nuclear workers inhale plutonium after bag breaks

8. Can you site a single authoritative book?

Since you've read more than one and all.

You'll note that I actual provided a reference in the post I pointed you to.

Here's another:

It allows you to calculate the specific lifetime cancer mortality risk coefficient (based on the more conservative LNT assumptions) for the amount inhaled (20,000 Bq is approximately half a million picocuries).

If the math is too difficult, you can see your memory (or the book you remember) debunked quite effectively in the prose summary:

"breathing in 5,000 respirable plutonium particles of about 3 microns each is estimated to increase an individual’s risk of incurring a fatal cancer about 1% above the U.S. average."
