The Device
The device consists of two constituent parts, a gamma radiation sensitive inner core which fits inside the spherical tungsten outer collimation sheath. The outside diameter of the device is 140 mm (approx 5 ½ inch) which allows deployment in to hard to reach areas whilst providing a 360 degree view of the area. The inner core is made up of material which changes colour when it is exposed to gamma radiation. Therefore, when the device is deployed inside a radioactive environment the collimation device preferentially allows gamma radiation to pass through the collimation holes which deposits tracks within the inner core. These tracks can then be analysed to provide a 3D visualisation of the radioactive environment predicting both source location and intensity.

Famous quotes containing the word device:
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (1856–1950)
“Corporation. An ingenious device for obtaining individual profit without individual responsibility.”
—Ambrose Bierce (1842–1914)
