QUICK SWEEP RAD DETECTOR

Model # P-8Neon

LOCATE X-RAY LEAKAGE or ALPHA, BETA, GAMMA 
CONTAMINATION ON:

* X-RAY SCANNERS

* PACKAGES

* FLOORS OR WALLS

APPLICATION: State and Federal Regulations require that 
devices that use or produce X-rays must not emit (leak) 
X-rays in excess of 0.5 mR/hr from any 10 cm$^{2}$ area as 
measured at a distance of 5 cm. This should be verified 
by complete measurement at time of manufacture, again, 
upon installation, and periodically thereafter. A small 
accurate X-ray mR-meter such as Technical Associates 
Model TBM-EXR with 10 cm$^{2}$ active detector area is ideal 
for this task. However, manually scanning the surface 
of a large cabinet x-ray machine or airport luggage 
scanner, etc. 10 square centimeters at a time is quite 
tedious. For this reason, Technical Associates offers 
the Quick Sweep Rad Detector Model P-8NEON.

1. Pick one side of X-ray cabinet to check first. 

2. Use chalk to divide this side of cabinet into 
  regions or strokes, each 16" wide. 

3. Set X-Ray emitter to continuous emission or 
  continuous use if possible. 

4. Place P-8NEON Probe against side of cabinet and 
  sweep it along at about 1"/second.

5. Watch the 8 lights on the P-8NEON for rapid 
  flashing. 

6. Use the chalk to mark the location of the flashing 
  light. 

7. Then continue your sweep. 

8. When sweeps are completed, come back and repair 
  shielding at the "hot spots" or measure precise mR/hr 
  with TBM-EXR.

SPECIFICATIONS:

Detector: Sensitive Area 2" x 16" 
Window 1.5 - 2.0 mg/cm$^{2}$ 
Measures Alpha, Beta, Gamma, X-Ray.

Optional Ratemeter: (See LAM-10 ratemeter spec sheet.)

Locator Lights: 8 Large Red LEDS or Neon lights pinpoint 
which of the 8 detectors is firing, i.e. detecting an 
X-ray leak.

Options: Meter shows total count-rate.
Red light and audio alarm show if total count-rate is 
above preset users level.(User settable)
Audio emits clicking sound.
