Notes

Federal Maritime and Hydrographic Agency (BSH) 4

• Tritium: sampling successful in 2016, measurements still pending (problems with the low level scintillation counter)
• Sediment and suspended matter: sampling successful in 2015 and 2016 , measurements done,

results not finished yet

• KNiFC-PAN (potassium nickel hexacyanoferrate(II) based on polyacrylnitrile):

another adsorption material for caesium isotopes usage equal to KCFC (potassium cyanocobalt(II)ferrate(II)) tests are completed, submission of results to Applied Radiation and Isotopes at the beginning of April 2017 title submitted: Offshore concentration of caesium radioisotopes from large volume seawater samples using KNiFC-PAN
