Hi everyone this is my first time posting here,
First of all, excuse my english because here in Mtl we speak French mostly.
My team and I are working on an university project in Montreal (Qc) Canada (Polytechnique) regarding the recycling of radioactive material waste. We are working on the dismantlement of a Canadian nuclear facility (situated between Ontario and the province of Quebec, it's a fictive project, but the most realistic plant studied is the ''GENTILLY'' one) .
The first part of the project in due for this coming Wed nesday and we need to figure out a few things we couldn't find online. It regards the acceptable exposure rates / protection from gamma rays, some physics conversion we could not figure out and the concrete or carbon steel concrete for the confinement on the radioactive scorie (radioactive Ceasium).
1. How do we go about convertir Becquerels to mSv then to eV ? Is that even possible? Any pist of solution from your part? Here are the references we have used to far:

2. We need to figure out and come up with some NUMBERS for the confinement of the radioactive scorie (slag in english?). We thought about using the CSA norms N287 (N287.2 is unavailable at our university):

3. We are pouring the molten iron into a concrete tank, and we need to figure out how much concrete (standards, norms or fomulaes) needs to be used as an absorber to contain the radio active slag.
4. We are using two ovens to melt the radioactive iron. We need to figure out a way to transport the molten iron from oven01 to oven02 (potentially through concrete pipes, but we cannot figure out the thickness recquired to ensure staff safety).5. We need norms and standards (Canadian or American) for staff exposure to radioactive substance in the facility altoget her.Références :

6. We know that we will have to use robotic arms and proper PPE (personal protection equipment) to deal with all this radioactive waste. Are there any formulaes that can help us with the radioactive emission linked with thickness of protective absorbent concrete pipes, equipments ?
Thanks a lot for any reference, formulaes or solutions from your part. Please if you are a phD student working on similar thesis, or an industrial, we need concrete and clear sources as our project in for a real mining company in Quebec, Canada.Cyril St-Amand
