So how is a becquerel different from a hertz? 203.82.183.147 14:56, 27 Feb 2005 (UTC)

becquerel are used only in the field of (ionizing) radiation AnyFile 15:37, 3 Mar 2005 (UTC)

"Reciprocal second"?

The article says:

It was designated, in the SI, to use the becquerel rather than the reciprocal second for the activity measure unit. This unit was specifically introduced because of the dangers to human health which might arise from mistakes involving the units reciprocal second. Using the becquerel unit a more active (and so, all the other things fixed, more dangerous) source has a higher number. Using 1/s or s as a second instead may lead to confusion.

How so? How would using a unit like, for example, "Emissions per second" (or "eps") result in confusion? A higher number would still indicate greater radioactivity. —The preceding unsigned comment was added by 69.181.75.84 (talk • contribs) 14:23, 19 May 2006.

That's exactly what a becquerel is; a shorthand for "the activity of a quantity of radioactive material in which one nucleus decays per second". The sentence about proportionality wasn't very clear in the article - I've edited it so it's a bit better, I hope. --HughCharlesParker (talk - contribs) 11:51, 28 February 2007 (UTC)[reply]

Example of "typical" levels?

The article does not give any feeling how much is one becquerel? One giga-becquerel? and such.

An example can be one kg of granite (which is a bit more radioactive rock than average), approximately how many becquerels is in it?
