Course Descriptions

Calibration Training

We offer an intensive two day training course that involves calibration of Ludlum manufactured instruments. This course is intended for customers interested in performing their own calibrations. It is generally not intended for first-responders or survey technicians since it does not cover the health physics aspects of radiation surveying.

The course is held at Ludlum's main facility in Sweetwater, TX and at Protean Instrument in Knoxville, TN. It is offered at no charge; however, attendees are responsible for accommodation and meals. Training is usually scheduled around middle of the month, but other times can be arranged for groups of four or more (see schedule).

Scheduled classes are held Tuesdays & Wednesdays, and classes start at 8:30 AM each day.

Note: Prior health physics training is recommended.
