How to use the tables?
Listed are the isotopes that are compulsive by the AVV-IMIS (Allgemeine Verwaltungsvorschrift zum Integrierten Mess- und Informationssystem zur Überwachung der Radioaktivität in der Umwelt nach dem Strahlenschutzvorsorgegesetz vom 13. Dezember 2006), plus, in some cases, other interesting nuclides.
If the sign "<" is put in front of the value, the activity-concentration of the corresponding isotope is below the detection-limit represented by that value.
Every sample has a sample-number (HPN). In some cases, the same HPN is listed more than once. This means that more than one analyzing-procedure has been applied to this sample.
In order to keep the tables clearly arranged, no uncertainties for the measured values are given.
For comparison of our results, you find the annual reports of the "Bundesamt für Strahlenschutz" (Jahresberichte Umweltradioaktivität und Strahlenbelastung des Bundesamtes für Strahlenschutz) here.
