Frikkie,

Before simply using a fixed background subtraction, one really needs to know the actual backgroun, and, the variation of the background changes, seasonal as well as othe influence quantities that affect the background. If not, the probability of false positives or negatives, as well as over or under estimation of dose can be the result.

Regards,
