Before we can discuss the effects of nuclear radiation, it's necessary to get a handle on the units used to describe it. There are a whole lot of weird ones out there; you can be probably guess that a
Curie is a measure of radiation of some sort, but what's a
Sievert? It sounds like a type of cat. And what about a
Becquerel - that sounds like a cute little marsupial. A
REM? Is this something to do with sleeping?
Today's lesson is a basic guide to the two most important quantities that we will be discussing;
Radiation Dose and
Radiation Dose Rate. To keep this post a manageable length, I will only write about the units used to describe these quantities and won't go into how to measure them or what the effects of various doses are. (BTW, while I will mention various specific doses and dose rates for the purposes of illustration below, you can ignore the actual numbers for the time being.)
