2.6 Multiple RAD7s

Before using the Operational Check to check a RAD7, the Operational Check must be left sealed for a

month, in order for the radon inside the container to reach equilibrium. That means a RAD7 can have

its operation checked each month on a regular basis. However, there is nothing to stop us hooking up

multiple RAD7s in series in the loop connected to the Operational Check. This increases the volume of

the loop and hence decreases the radon concentration in the loop. This method is recommended for

checking up to six RAD7s on a monthly basis.

Each month, all four RAD7s can be connected in series with one another and thoroughly purged and

dried out, before being connected to the Operational Check to check that the instruments are counting

and obtain spectra. During the measurement all the RAD7 pumps, except one, should be set to OFF
