VERY LIMITED STOCKS - DON'T MISS OUT!
Here’s a really unusual and highly affordable little instrument for detecting both Nuclear and Electromagnetic Radiation. It's for everyone who takes an interest in their environment and with just a handful of controls it is really easy to use and understand.
First off it’s a fully-fledged and very capable Geiger Counter/Dosimeter, sensitive to Beta, Gamma and X-Ray radiation. It’s no slouch either; able to detect and measure normal background radiation and, therefore, alert the user to elevated levels that could be coming from things including antique clocks and watches, natural minerals (such as granite). Other detectable items include antique glassware, ceramics and domestic smoke detectors.
Readings, in standard dose units
of microsieverts per hour (mSv/hr),
are updated once a second so it’s useful for urban prospecting. Additionally
there is a discreet built-in sounder that clicks with every ‘event’ and sounds
an alarm when the real-time dose exceeds the preset threshold of 0.5 mSv/hr.
There’s more. The large, bright, back-lit colour LCD also
shows Mean and Cumulative dose, plus it has a constantly updated trend graph.
Cumulative dose readings are stored in a non-volatile memory that maintains
readings, even when the unit is powered down. Speaking of which, it run on
three standard or rechargeable AAA cells (1.5 or 1.2v) with the latter charged
via a USB socket on the side.
So far so good, but at switch-on there’s the option to
select either Nuclear radiation – see above – or Electromagnetic radiation. This
is emitted by almost all electrical devices, from mobiles to microwave ovens,
TVs to toasters and waffle irons to Wi-FI routers.
You get the picture and we’re not going to get into the whole 'is it harmful or not' argument, but there is no denying that emanations from
electrical appliances genuinely concern a lot of people. This little gadget
tells you how much of it there is and, potentially, where it is coming from.
The display shows Power Density in microwatts per square
Electrical Field Intensity is shown in volts per metre (v/m) and there’s a
combined magnetic field strength and trend graph display showing measurements
in micro-Teslas (mT). Place it near virtually any electrical
device and watch the numbers shoot up! This makes it simple to identify the
devices that put out the most electromagnetic radiation, and the areas of your
house or environment most affected.
Please note that this device is not being
sold for use in health or safety applications, but it does clearly illustrate
how pervasive electromagnetic radiation has become in our gadget and gizmo
