Millirem to becquerel
Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

What is the conversion factor for millirem/becquerel?

No simple "conversion" is possible as they are different things and the calculation is complex.
The becquerel is a measure of nuclear decays per second from an amount of material. It is indifferent to whether the emissions are alpha particles, beta particles, neutrons, gamma rays, etc. To get to absorbed dose, you need to know the number of each type and energies.
Absorbed dose measures the energy absorded per kilogram and has to consider the energy type, the amount of energy per particle, the probability of absorbtion (gamma rays may pass right through). For effective dose, sieverts or rems, a "quality of radiation" is also considered as some do more damage.
I'm an engineer and I couldn't find any guides on the web that would make me feel competent to do the calculation vs discuss the complexity. This link might be a start at understanding it.
