We also construct custom made radiation monitors, for example the RM-G90-3 with three RM-G90 type tubes. These have a gamma sensitivity of 28,800 cpm/mR/hr, Cs137 gamma, and operate the same as all our RMs, i.e. directly connected to a serial port, our USB-MSP and/or our LCD-90.

When two RM-G90-3 devices are connected to our Coincidence Box and placed directly on top of each other, they provide a Cosmic Ray count rate of ~140 Counts per Minute.

    E-mail questions received:

    > I have 2 of your RM-80 units, and was curious about the Coincidence Box Decoder.
    > 1) Does the Coincidence Box power both units from the serial port(s), or does it require a battery?
    Both units and the Coincidence Box are powered from one serial port no problem.

    > 2) Does it require 2 serial ports?
    Only one serial port is needed for the coincidence counts. If you want also to gather rad data from the two RM units at the same time, an extra serial port per RM is needed, for a total of three, that is, one serial port for the coincidence counts and one serial port for each RM. In this case, the telephone cable from each RM is split into two lines with a telephone line splitter ($1.00). One of the lines from each RM goes to the coincidence box, and the other line goes to one of the serial ports.

    > 3) Do 3 separate graphs result (one from each unit and a coincidence one?
    Yes, with the above setup. Otherwise, with one serial port, just coincidence counts are plotted.

    > 4) Could a fan-filter be put on one and still have it record the coincidence counts?
    Coincidence counts result when an ionizing particle passes through both tubes. The closer the tubes, the more likely a muon will pass through both. You could place one RM-80 with fan-filter on top of the second RM-80 such that a good percentage of the muons passing through the RM-80 with fan-filter will also pass through the other RM-80, if both windows are oriented horizontally, since the majority of muons pass vertically from the sky down.
