1.3 Before You Start - Safety Precautions

This product is designed for quality assurance testing of therapeutic radiation treatment machines. It is not for machine calibration nor is it intended as a substitute for a precision dosimeter system (Farmer-type Probe and Electrometer with official calibration). Its use should be restricted to the monitoring of constancy of output, flatness, and symmetry. It is the responsibility of the user to establish the correct procedure of uses including the initial configuration of the device, (via the Customization program included). Quality assurance testing should be done by qualified personnel under the supervision of a trained medical physicist. The Model 90100 TRACKER System should be used only by people who are:

•aware of and understand the limitations of the device as they relate to the measurement of radiation output;

•knowledgeable about safety procedures observed when working with radiation sources, such as therapy radiation machines;

•aware of safety precautions required to avoid possible injury when using electrical/electronic equipment.

Please take the time to read this manual carefully before operating this instrument.
