Authorised preparation* for investigating the characteristics of radioactive radiation, particularly for advanced energy-analysis experiments with the semiconductor detector (
559 921) or the scintillation counter (
559 901). * According to German legislation (StrlSchV) it is generally not necessary to obtain a specific permit when handling authorised samples, as long as the total activity, as calculated by the stipulated summation formula, does not exceed the authorised limit.
