Alpha-activity of bricks



Dear Radsafers,

does anybody know the alpha-activity of bricks ?

We know the following things:

1) there is the alpha activity from U-238, U-235 and Th-232 with all the

members of their decay series.

2) our results of alpha-activity-measurements are between 0,7 Bq/g and 20 Bq/g

Let us know, what is Your experience.

Thanks in advance.
