If radiation causes cancer then, yes. I read that dental xrays can cause it too in the case of excessive xrays over time. It may take ten or twenty years to contract, though. I can imagine that the victims’ family might say, “we don’t know why he/she got cancer. It’s from our air, food and water” when, in fact, it will be from the airport xrays. But this is just my opinion. I can foresee the airports reducing the rads too , eventually, due to cancer concerns just like what was done with mammograms.
