I didn't say radiation exposure, I said radioactive particulates in my body. 0.1% increase in radiation exposure is a high altitude plane flight. Nothing to be concerned about as you say. 0.1% increase in radioactive particulates in my body is a Fukishima sand grain in a clam. Or a leaky medical iodine cell. Or a speck of Chernobyl ash stirred up by passing soldiers and inhaled. That's a much bigger concern.
