Neutron Fluence Measurement Using Common PNP Transistors
PNP Transistors (2N3906) were tested at Missouri S&T research reactor to investigate the feasibility of using them as a neutron fluence measurement system. Initial results are promising; these relatively inexpensive devices can provide quite accurate neutron fluence measurements. PNP transistors were tested between 10 n/cm² - 8 1014 n/cm². These fluence values are typical for a test reactor. For cumulative fluence above 10 14 n/cm², change in transistor gain exhibit good linearity.
