Introduction; How The Inspector+ Detects Radiation; Precautions - Radiation Alert Inspector + Manuel D'instructions

1 Introduction

The Inspector+ is a health and safety instrument that is optimized to detect low
levels of radiation. It measures alpha, beta, gamma, and x-ray radiation.
Its applications include:
• Detecting and measuring surface contamination
• Monitoring possible radiation exposure while working with radionuclides
• Screening for environmental contamination
• Detecting noble gases and other low energy radionuclides

How the Inspector+ Detects Radiation

The Inspector+ uses a Geiger-Mueller tube to detect radiation. The Geiger tube
generates a pulse of electrical current each time radiation passes through the
tube and causes ionization. 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 radioactivity. A reading is expressed more accurately
as an average over time, and the average is more accurate over a longer time
period. For details, see "Operating in Total/Timer Mode" in Chapter 3.

Precautions

To keep the Inspector+ in good condition, handle it with care, and observe the
following precautions:
• Do not contaminate the Inspector+ by touching it to radioactive surfaces
or materials. If contamination is suspected, replacement rubber strips are
stapled inside this manual.
• Do not leave the Inspector+ in temperatures over 100° F (38° C) or in
direct sunlight for extended periods of time.
• 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.
