The Effect of Windspeed on the Miotogenic Potency of GB and VX Vapour
Abstract
The relationship between wind speed and the potency of GB and VX vapour for the production of miosis has been studied in rabbits and humans. Changes in windspeed have a small effect on the degree of miosis produced by GB vapour. The Ct to produce 90% miosis in humans at a wind speed of 0.01 m/s is 10 mg min/cu m and at 2 m/s is 4 mg min/cu m; with VX vapour, however, the Ct to produce 90% miosis falls from 7 mg min/cu m at 0.01 m/s to 0.09 mg min/cu m at 2 m/s. This difference between the effects of GB and VX vapour at varying wind speeds can be explained in terms of the physico-chemical properties of the two agents. A mathematical model has been developed which gives good agreement with experimental results.
