1 Introduction
The Radalert™ 100 is a health and safety instrument that measures
alpha, beta, and gamma radiation. With the Radalert 100, you can:
•
Monitor possible radiation exposure while working near
radionuclides
•
Ensure compliance with regulatory standards
•
Check for leakage from X-ray machines and other sources
•
Set the alert level and use the Radalert 100 in Alert mode; if
the radiation goes above the level you set, the alert beeper
sounds to let you know
•
Screen for environmental contamination or environmental
sources of radioactivity
•
Connect the Radalert 100 to a computer or data logger to
record and tabulate your data
This manual gives complete instructions for using the Radalert 100
and procedures for common applications.
How the Radalert 100 Detects Radiation
The Radalert 100 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
Radalert 100 displays the counts in the mode you choose: counts
per minute (CPM), milliroentgens per hour (mR/hr), or total counts
for a timed period. In SI units, counts per second (CPS) and
microsieverts per hour (
µ
Sv/hr) are used.
