Chapter 1: Introducon

The Inspector is a health and safety instrument that is opmized to detect low levels of radiaon. It measures

alpha, beta, gamma, and x-ray radiaon (ionizing radiaon only).

Its applicaons include:

• Detecng and measuring surface contaminaon

• Monitoring possible radiaon exposure while working with radionuclides

• Screening for environmental contaminaon

• Detecng noble gases and other low energy radionuclides

How The Inspector Detects Radiaon

The Inspector uses a Geiger-Mueller tube to detect radiaon. The Geiger tube generates a pulse of electrical

current each me radiaon passes through the halogen quenched tube and causes ionizaon. Each pulse is

electronically detected and registers as a count. The Inspector displays the counts in the mode you choose.

The number of counts detected by The Inspector varies from minute to minute due to the random nature of

radioacvity. A reading is expressed more accurately as an average over me, and the average is more accurate

over a longer me period. For details, see “Operang in Timer Mode” in Chapter 3.

Precauons

To keep the Inspector in good condion, handle it with care, and observe the following precauons:

• CAUTION: Never touch the Inspector to a surface that may be contaminated. You may contaminate the

instrument.

• Do not leave the Inspector in temperatures over 100° F (38° C) or in direct sunlight for extended periods of

me.

• Do not get the Inspector wet. Water can damage the circuitry and the mica surface of the Geiger tube.

• Do not put the Inspector in a microwave oven. It cannot measure microwaves, and you may damage it or the

oven.

• This instrument may be sensive to and may not operate properly in radio frequency, microwave,

electrostac, and electromagnec elds.

• If you do not expect to use The Inspector for longer than one month, remove the baery to avoid damage

from baery corrosion. Change the baery promptly when the baery indicator appears on the display.

• CAUTION: When using the unit at altudes higher than 8000 feet (2438.4 meters), it is possible that the tube

window can rupture.
