H3R 7000 - AIRBORNE TRITIUM CONDENSER

The H3R 7000 is an innovative instrument in the field of Tritium in air sampling. It collects samples of Tritium in its vapour form and produces results in less than 40 minutes.

The sample obtained can be measured down to a detection limit of 0.01 Bq/m3 by deferred measurement using liquid scintillation.

The operating principle is based on a french patent which has been deposed at an internationnal level by the french institute of radioprotection (I.R.S.N) and the military school of atomic energy of the french navy (E.A.M.E.A).

Operating Principle

This equipment collects the Tritium in its vapour form by a cryogenisation process of the water vapour in ambient air. At the same time, it measures absolute humidity of this air in order to know with accuracy the water quantity per cubic meter of air, absolute humidity being expressed in g/M3 or ml/M3.

On average, less than 40 minutes is needed to collect enough quantity of water to carry out a deferred measurement of Tritium activity contained in the water using liquid scintillation counting.

After measurement, the tritium activity is expressed in Becquerels, and converted to obtain a tritium activity in Becquerels per cubic meter (Bq/m3).
