In the Radiographic Testing (RT) Level I course, the student will learn the theory and principles of radiation and how they apply to the basics of radiography.

There are many variables to be controlled in order to produce a high quality image. RT is one of the major volumetric methods with Ultrasonic Testing being the other. Subjects also include the development of RT techniques for a wide range of applications, handling and processing radiographic film, and the safe use of RT equipment.

Safety is of paramount concern when dealing with radiation sources and the means of monitoring and minimizing exposure is essential. Both X-ray and Gamma Ray sources are discussed along with technique development guidance.

This program is the beginning step for those who will be seeking a career in RT as practitioners. It is also appropriate for other personnel who want to understand the basics of Industrial Radiography. Common applications as well as the need to maintain complete records are also presented.

NDTclassroom.com's Radiographic Testing I training is a completely video based online course taught by Gary Larson that covers:

- Principles of radiation

- Radiographic Testing theory

- How to perform RT examinations

- Techniques used to perform RT

- Procedures used to perform RT

- Requirements of RT

- How to interpret and evaluate test result

This course meets the reccomendations for training laid out in SNT-TC-1A and covers the Body of Knowledge for CP-105.

NOTE:  There is REQUIRED READING assigned at the beginning of the course.  Reading assignments will be prepared and provided to each student with a list of references and books relative to the subjects. Self-study will be strongly encouraged which will add to the overall training time to be credited. It will also better prepare the student for the practical lab/’hands-on” session to follow. It will be the responsibility of the student to maintain a log of self-study time. It is recommended that the applicable Level III be involved and sign off the assignments as completed. This should become a part of the training records for use with subsequent certifications.   s

Radiographic Testing Level II is a continuation of the RT Level I course and expands on the duties and responsibilities of the RT practitioner.

It begins with a review of the basic Level I subjects and continues with a more in-depth presentation of how to control the variables to produce an acceptable radiographic image. Emphasis is placed on how to achieve high sensitivity through optimizing contrast, definition and film processing. The quality level of an RT image is established by devices referred to as “Image Quality Indicators” or IQI’s. The acceptability of the radiograph is determined by the image of these IQI’s. The interpretation and evaluation of the radiograph is a key element of RT and is covered in depth.

This course is essential for those who have completed RT I and want to advance to this higher certification level.
