Calculating X-Radiation Equivalent to 20mR/h

[nonphysical]

1. How many mSv/h of x-radiation is equivalent to a dose rate of 20mR/h?


2. The relationship between the sievert and the Rem is i believe isievert = 100 Rem



3. answer i think 2000mSv/h

welcome to pf!

hi nonphysical! welcome to pf!

yes, from http://en.wikipedia.org/wiki/Sievert#SI_multiples_and_conversions" …

An older unit of the equivalent dose is the rem (Röntgen equivalent man); 1 Sv is equal to 100 rem, for a quality factor Q=1.

but a Sv is bigger than a rem, so the answer should be … ?

Thanks Tiny-Tim
So there must be a better way of expressing the answer?

 

[nonphysical]

Thanks for your help.
I'll write the answer as above. I don't know any other way.

(just got up :zzz: …)

1 Sv = 100 rem

so 1 mSv = 100 mrem

so 2 mSv = 200 mrem

so … ?

Tiny-tim,
Thanks again, i think i have a better grip on the concept now.

1 Sv = 100 rem
1 mS/h = 100 mR/h
so 20mR/h =0.2 mS/h

Woohoo! ​
