incidentally, just got off the phone & ran your reading by the individual who had considered buying this older model Submariner...he said the one he tested gave a reading of 0.3 uSv/h.
I would imagine that the RSC (or any watchmaker) neither appreciates/enjoys/or looks forward to these kinds of watches coming in for periodic servicing. being that radium is easily ingested via breathing and/or soft tissue contact, pro-active precautionary measures must be taken when opening them up.

It is a good device to have for little more than $110 - especially if you are going to be handling vintage parts that might be radium. I have purchased several sets of hands from various vintage markets and off the Bay that were radium and cause a lot of clicking noise.
0.3 uSv/hr is actually not bad. 3 my concern would be elevated. 0.3 is like eating 3 bananas per day
Good chart here on relative doses (I am not professionally trained in this):
