Description
Sealed preparation with measured activity, for calibrating a measuring station for e.g. environmental samples in reference geometry; as the activity is homogeneously distributed over the entire volume of the Marinelli beaker at a density of 1 g/cm3, the calibrating preparation is also suitable for determining the activity of aqueous samples. With certificate of calibration with an accuracy of ±10%. * 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. Educational establishments should consult with the responsible authorities as to whether additional regulations need to be observed.
