Hi all. Another thing we have noticed is that for all non-4SC monitoring, Alpha Tracker reports to 3 decimal places if the number of fields counted and volume of air sampled gives a LOQ of less than 0.010, even though 248 states only clearances need to be reported to 3 d.p. So we have had reported results for reassurances or backgrounds of <0.008, which I believe should be reported as <0.010 according to 248. They said they would canvas other users as no one else has mentioned it…
