? Calibration of the pMOS dosimeter at VT mode has been carried out for the irradiation of 60
C
o gamma rays or 6MeV electrons It is shown that
at the dose range larger than 102Gy(Si)
the response curve of threshold voltage shift to irradiation dose is linear and the sensitivity of the pMOS FET to irradiation is 20mV/Gy(Si) which is suitable for the use in the space radiation environment The sensitivity to 60
C
o gamma rays is about 13 times of that to 6MeV electrons Considering the dependence of sensitivity of the pMOS dosimeter on the sort of irradiation particles
a calibration method for a mix-irradiation field is suggested
