First, the units of the report are Bq/kg not counts per minute (CPM)

Second, when using a germanium detector your minimum detectable level is a function of the size of your sample and the amount of time you spend counting photons.

You can cut your minimum detectable amount in half by counting photons for four times as long.

You can cut your minimum detectable amount in half by doubling the size of your sample.

You don't always get to have as large a sample as you would like and there are only 24 hours in each day so you have to make a choice about testing many samples for a short period or one sample for a long period.
