A controlled release of 256 TBq of pure dry tritium through a 40-m high stack was performed in France, on October 15, 1986. Air measurements were assigned to the Health Physics Division (SPR) from the Centre of Bruyeres-le-Chatel and soil measurements in particular for deposition velocity and reemission rate, to the Division for Studies and Research on the Environment (SERE) of the Institute of Protection and Nuclear Safety (IPSN). The main conclusions were: concordance between code predictions and air measurements; HTO increase in the air originating from soil effects; HT deposition velocity: 1 ..-->.. 5 E-4 ms/sup -1/, reemission rate: 5 % per hour.
