There are provisions in the trade agreement to adapt to specific requirements of each of the host countries. On the specifics, I'd have to look at that one in particular, but obviously radon gas is not an issue. You have to look at each case where you're restricting because essentially you don't want to set a standard that you can then be challenged on as having put up a barrier to trade. So that's the trade-off, and part of our working at the international level is to ensure that there's alignment across those things and that the needs are real, not created.
