Determination of Ra-226 and Rn-222
An "old method in a "new" frame

This method offers an easy way for:

  • The determination of Radium-226 in water and in soil by using of the Emanation-Method for sample preparation and the new designed Scintillation-Chamber (Lucas-Cell) for measurement
  • The determination of Radon-222 in water and in the air
  • Measurement of the activity-concentration in a Scintillation-Chamber and an Alpha-Scintillation-Counting-System with 16 channels

Including software for the calculation of:

  • Ra-226 concentration in water and in soil
  • Rn-222 concentration in water and in the air
