Further data ar: tevded - especially for the yeaws
L35L, 1952, 1987 and 1355.
To allow tar cirferent time: of arrival.
I have atiusted atic concen-
trations to a common relerence time of 1 day, after wot nation assuming a
(time) 1*¢ variation in activity.
Unfortunately, reference

In some cases a mumber of air samples were taken scrially during a 24
hour period.
In such instances each adjusted air concentration was multi-
plied by the fraction of a day it was sampled.
Then these results were |
added to obtein the weighted average concentration for the entire 24 hour
period.
If one assumes 2 proportionality between beta activity in the air and
yi3t reaching man through the food chain it is possible to crudely estimate
thyroid exposures for those years for which air data are available.
