ABSTRACT:
This invention provides a direct reading solid-state dosimeter which will measure neutron and gamma radiation. A dual metal-oxide-semiconductor field-effect transistor (MOSFET) is used as a gamma sensor and a forward biased PIN diode as a neutron sensor. A liquid crystal display is provided for displaying the gamma and neutron radiation dosage.
