On a Montreal-Fredericton flight in October, 1976, we measured the dose rate with a sensitive radiation monitor. The results are given in Figure 3.1. As you can see, the ground level dose rate was about 0.10 μGy/h; whereas, at the maximum flight altitude (8.8 krn or 29,000 ft), it was about 2.0 μGy/h. The total excess dose for the Montreal to Frederickton flight is only 0.7 μGy.
ICRP 60 uses the term "deterministic" to replace "non-stochastic". We'll stick with what we're used to from ICRP 26. Let's digress for a moment to give you a couple of everyday examples of non-stochastic and stochastic effects. Sunburn has a threshold; above this threshold exposure, the degree of sunburn becomes more and more severe with increasing exposure to the sun, and below the threshold no harm is done. Compare this with winning a million bucks in a lottery; this is pure chance - the probability depends on the exposure (the number of tickets you buy), but the magnitude of the effect doesn't change. You either win a megabuck or you don't.
A radiative transfer model determines the flux of UV radiation for a range of wavelengths. An action spectrum weights the response of the human skin to UV radiation at each wavelength. Once weighted, the flux values are integrated over the entire range, resulting in an erythemal dose rate — the instantaneous amount of skin-damaging radiation reaching the surface
