Handheld detection devices, sometimes referred to as Geiger counters
, are appropriate for analyzing small amounts of scrap at close range, while small area units can be mounted to analyze small trucks and containers, though neither is sufficient to detect radiation in a large truckload of scrap.
His latest challenge is to promote Geiger counters
as a vital household convenience.
The National Research Council loaned Spinks the basic equipment to work with radioisotopes: a scaler, several Geiger counters
, some lead bricks, and a 250 mg radium-beryllium neutron souce that could be used to make small amounts of radioisotopes.
And they sent a monitoring team armed with geiger counters
to find out if ex- Dounreay director Gerry Jordan's garden GLOWS.
In the glum silence, I became aware of the twitter of nesting barn swallows over the staccato accompaniment of the Geiger counters
. Larsen and I watched the birds flit among radioactive construction cranes sacrificed to the cause of the sarcophagus.
For example, the authors describe community concerns over media reports of increased cancer in the area and state personnel dressed in "moon suits" carrying instruments that look like Geiger counters
. The story then jumps forward five years.
He placed two Geiger counters
(see 1908) one above the other and set up a circuit that would record an event only if both counters recorded it virtually simultaneously.
To figure out where the drugs are going, they lace some opium with radioactive tracers so they can track it with Geiger counters
. They then follow the drugs as they are slowly dispersed throughout Europe.
? Will visitors to any resulting exhibition be required to don radiation suits?
With entertaining references to the movies and amusing anecdotes, Parker explains in easily understood terms the physics behind skydiving, holograms, autogiros, electromagnetic pulses, Geiger counters
, hydrogen bombs, and other nifty devices.
Once upon a time,an expeditionary force was sent to a North Wales chippy with Geiger counters
converted to pick up calorie radiation.
Mr Boardman said: ``If you start passing geiger counters
over an airport queue that would only increase anxiety, so you need a covert method of detecting the low intensity radiation emitted by such illegal substances, so preventing terrorist attacks.''
