First of all, I believe you're mixing several items here. Let me start at the back and say that all of our releases are controlled and monitored and they all fall orders of magnitude below regulatory limits. That's the start.
The second piece is that tritium is a radioisotope, it is hazardous, so in the workplace we treat it as a hazardous material. We monitor levels and provide protection for workers if they have to work in environments with significant tritium levels.
