Hi Clay,

The original UradMon A3 (https://www.uradmonitor.com/) had, along with
various other environment sensors, a gieger counter that registered in
cpm.

I've recently updated that driver
(https://github.com/glennmckechnie/weewx-uradmon) for it to return
microSieverts/hour rather than its default of cpm.

Rather than use the inbuilt group_radiation which defaults to W/m2 (as you 
note); I
created group_ion_radiation (ionizing) and set cpm, micro_sievert_hour as
its units.
That gave the flexibilty to enforce its unusual, but default, cpm
value; convert to micro_sievert_hour and keep it all self contained
(for the driver only). It also uses other units which are now in
weewx, but weren't when the driver was written. I've kept them for
backwards compatability.

Link to the code follows.
