| Resumen: | This standard specifies a method for the measurement of 99Tc in all types of waters by inductively coupled plasma mass spectrometry (ICP-MS).The method described in this standard, using currently available ICP-MS, has a detection limit of approximately 0,2 to 0,5 ng x l-1 (0,1 to 0,3 Bq x kg-1), which is much lower than the WHO criteria for safe consumption of drinking water (100 Bq x l-1). The method presented in this standard is not intended for the determination of ultra-trace amount of 99Tc. |
