In order to determine the level of radiation with which you are dealing, you may wish to take measurements with a gaussmeter
. There are many available on the market in the $100 to $200 price range.
The dc magnetic fields are transmitted through the check valve and detected externally at one or more locations by a magnetic field sensor such as a gaussmeter
that employs a Hall-effect probe.
The magnetic field measurements were made using a GM-700 Gaussmeter
Green Alternatives magazine sent its staff into their local community with a gaussmeter
, a device designed to measure the strength of electromagnetic fields, and found potentially dangerous levels in some unlikely places - a staffer's dishwasher, and a local lunch hangout which may have had faulty wiring.
