[ RadSafe ] Conversion Bq-Sievert

[Carol Marcus]

Feb. 3, 2019

Dear Theo:

You can't convert them.  They are units of different things.  The Bq is 
a unit of activity, and the Sv is a unit of equivalent radiation 
absorbed dose.

Best, Carol

As a journalist I am writing about the late Eben Byers who died in 1932 after swallowing - as he said 1400 bottles of Radithor of which each bottle contained 74 kBq (half radium 226 and radium 228). He swallowed it during 3 years, and then lived/suffered for 2 years until his death. 30 years after his death Robley Evans analysed his remains and concluded that Byers bones contained 225 kBq. Expected was about a 100 so Byers may have underreported his consumption. That being what it is I would like someone  someone to calculate from this 225kBq Byers lifetime dosis in Sieverts. I am  building a website  (popular, in Dutch) with the aim to fight  radiofobia and that requires imho t'hat I keep the usage of units limited and as uniform as possible. Anyone?
