This circuit uses a diode as a radiation sensor. The operational ones are old because the publication is from the 80's, but modern low voltage equivalents can be tested.
This circuit is an alternative to the previous circuit. We found it in the same article in the...
We found this circuit in Ferranti's 1974 transistor manual. Transistors are general-purpose types...
The connection of high-value input resistors causes the circuit to behave like a conventional...
