Calibration & Repair Training FAQ

1)  What is the cost of the Instrument Repair & Calibration Training and when is it offered?  

LMI offers this training at no charge when conducted at our factory location in Sweetwater, TX.  Accommodations and meals must be provided by the attendees.  Training is scheduled around mid-month and dates are listed on our website under the Support and Training tabs.  If you are interested in registering for this training, please contact us via e-mail at This email address is being protected from spambots. You need JavaScript enabled to view it..  Please include how many seats you would like to reserve and for which date. 


2)  What background do I need to take the training?

We strongly recommend that the participant have some previous training in the field of Health Physics, as we do not cover that in the training. Knowledge of the basic types and properties of ionizing radiation, as well as units of measurement, is necessary to get the maximum benefit from the training.  


3)  What do I need to bring to the training?

A scientific calculator is often useful, but not required.  A class handout and pen are provided.


4)  Upon completion of the two-day Instrument Repair & Calibration Training, will I be certified to perform instrument calibrations?

Ludlum Measurements is not a regulatory agency and can only certify our own personnel to perform calibrations. This is in accordance with our Radioactive Materials License issued by the State, which specifically authorizes the Company to perform Commercial Calibrations.

Only your State or a Federal Government Agency such as NRC or DOD /DOE can certify an organization to perform calibrations.
Ludlum Measurements will issue a Certificate of Training for the classroom hours attended.  Evidence of factory training is required by some States.


5)  Does LMI offer classes that will teach me how to use the instruments?

Unfortunately, no.  There is some limited information in downloadable videos on our website that offer basic information. These are intended for First Responders.  Ludlum Measurements is an Instrument Design and Manufacturing Company, but LMI personnel are not trained or certified in the field of Health Physics. We and our manufacturers' representatives do of course have many contacts in the Health Physics field and will be happy to provide you what contact information we may have for your area.


6) What will it cost to set up the equipment and sources for my organization to perform calibration?

There is no one-size-fits-all answer to this question. It is very dependent on the type and level of radiation that the equipment may see. At the very least, when instruments used to detect low levels of contamination will be used, a NIST traceable pulser and NIST traceable sources will be required. For instrument and detector combinations where the anticipated levels of radiation can be high, the cost and regulatory requirements will go up substantially. As a rule of thumb, we say $10,000 on the low end and $40,000 and up on the higher end, depending on the source(s) needed. Any calibration activity will probably require that you have a State Radioactive Materials License or one issued directly by the NRC (for non-agreement States).


7) Can I get copies of Ludlum Calibration Specs to review?

Yes, Ludlum will provide working copies of Cal Specs. These are controlled documents and only updated in house. Contact us at This email address is being protected from spambots.

8) Are the Calibration and Repair courses ever offered in my area of the Country?

Due to demand, courses are sometimes offered on the West Coast for a fee of about $650 per seat. This is usually in the fall in Monterrey, CA. Check our website in late spring if you are interested.


9) If my organization wishes to have the two-day class taught on site for a number of people, can that be arranged and what will be the cost?

Yes, Ludlum Measurements has a set of calibration benches on wheels that can be transported to any area of the country in our trailer and set up at your facility. The cost varies with location, but is normally in the $5000 to $7000 range for the two-day class for 10 people. Contact us for a specific quote.


10) Is the Calibration and Repair training approved for CEUs for CHPs?

Yes, the course is approved by the American Academy of Health Physics for 32 CEUs. The AAHP course number is 2015-00-028.
