RE: Activity and Dose Analogies
How about Bq's are the size of the pile, Gy's are the magnitude of the
stench and Sv's are the likelihood of you having a reaction to the stench.
Can you guess the material? Works great for people who have absolutely no
understanding about radiation but have to work around it for a short while.

Jim:
Yes, I like to use a light bulb analogy. Becquerels are the brightness of
the bulb, Grays are the brightness on a surface, like your skin, and
Sieverts are the probability of getting sunburn from that brightness.
I like the BBC's explanation of Sv: "In short, a Sv is
the most useful but complicated and subjective unit for measuring
radiation effects on people."
The boxer analogy is quite inventive!

Any more?

Mike,
I like this. I have used guns and bullets as an analogy often for the same
purpose and have often received comments that this might be too harsh and
scary an analogy. I must admit I agree. The boxer is still a bit violent
but less associated with death than a gun. Yet still something everyone is
familiar with.
I am sure there must be better than that still. Something less violent but
still physically comparable.
Thanks for the post Mike.
Any other good analogies out there?

Subject: BBC analogies
This showed up in a technical report I was reading. No reference was
given. I just thought it was interesting.
The British Broadcasting Company (BBC) has provided an illustrative
boxing analogy to contrast what is intended by the three international
radiation measures. It depicts, for the public, the qualitative
differences between Bq, Gy and Sv as:
Bq: " a measure of how many punches are thrown without regard to whether
they are roundhouses, hooks, jabs, or even if they connect at all."
Gy: "a unit that measures whether the punch is a strong uppercut or just
a little jab. However, the gray wouldn't show the cumulative effect of
something like 100 jabs to the exact same spot on the cheekbone versus
one hard punch to the solar plexus"
Sv: "useful in determining the likelihood that (the boxer) might suffer
some long-term damage as a result of this pummeling." "In short, a Sv is
the most useful but complicated and subjective unit for measuring
radiation effects on people."
