| Simulates eight different
source strengths - using only one source!
- Simplifies compliance with NRC and state requirements
- Checks linearity without sample decay or fractioning
- Covers diagnostic or therapeutic quantities in a single
pass
The Lineator is a simple device to accurately and reliably
verify the linearity of your dose calibrator. Test results are available
in minutes, without waiting days for decay, making it feasible to
perform a linearity test more often. Early identification can prevent
problems before they occur.
The Lineator is a set of five tubes. Four tubes are used to perform
the test and an interchangeable tube is used depending on the dynamic
range needed to cover.
To perform a linearity test, insert a source of Tc-99m of the maximum
activity to be measured into the central tube, then place the tube
into the chamber of your dose calibrator and count. The remaining
lead-lined tubes are placed, one at a time, concentrically over
the central tube and counted individually or in combination. The
readings are then normalized with predetermined factors, and the
degree of linearity can be seen virtually at a glance.
Using only one source, the Lineator can simulate up to eight different
source strengths. Each outer tube absorbs a portion of the source
radiation and reduces the effective source activity seen by the
dose calibrator.
