    Abstract

    Organic conductors are promising candidates for gamma dosimetry in the range of 104 to 108 Gy. Their electrical resistance increases with the absorbed dose, and this variation can be predicted theoretically over a large dose range. One of these conductors called (TMTSF)(DMTCNQ) has been tested in the industrial gamma irradiator of reactor Osiris at a temperature of 50°C. The resolution of this absorbed-dose integrator was shown to be better than 104 Gy for a maximum integrated dose of several 107 Gy. The measurement of this dosimeter in situ during irradiation permits accurate monitoring and control of the industrial irradiation plant for a period of several months.
