CHAPTER FOUR:
ATOMLAB 100 DOSE CALIBRATOR DESCRIPTION
OVERVIEW
By this point, you should have already setup, installed and
powered up your Atomlab 100 as described in Chapters 1, 2
and 3. Now, before getting into the actual operation proce-
dures, we suggest you take a few minutes and review this
chapter. It provides a complete description of the Display
and Detector units comprising your dose calibrator. For an
illustration of parts and components, refer back to "Packing
Slip", Figure P-1.
GENERAL DESCRIPTION
The Atomlab Dose Calibrators are used to measure the
radioactivity of a known radioisotope. Their primary applica-
tion is the measurement of the dose administered to a
patient in nuclear imaging. The design for both units incor-
porates unique electronics and software which surpass
stringent regulatory performance standards and provide fast
and accurate results.
The Detector Unit uses an ionization chamber for radiation
detection and an electrometer for ion current measurement.
The chamber bias is generated with an electronic high volt-
age supply, eliminating the need for expensive battery
changes. An optional Multi-Chamber Manual Interface is
also available.
The Display Unit communicates with the Detector Unit
through a serial port.
An optional RS-232 computer interface is available. This
interface will allow the user to send data and commands
between the dose calibrator and a remote PC.
