Abstract

A semiconductor of the MOSFET type of device is made in the form of a tube or pin. The tube or pin is of silicon, coated with silicon oxide except at the two ends where it is converted from P to N (for example by difusion) in the shape of rings. The surfaces of the silicon oxide and of the two rings are coated with metal to which are attached non-rectifying connections. The three connections form the terminals of the transistor device. Such a device can measure low radiations of beta, gamma and X rays, up to approx 50 Ke V,and of 102 to 105 rads, without disturbing the original field. The device is calibrated in a known field.
