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. W. H. Lang D.-Bonhoeffer-Str. 43 63110 Rodgau, Germany E-Mail fibonacci1@01019freenet.de |
