Radiography Testing II


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.’s Radiographic Testing II 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 results

This course meets the recommendations for training as described in SNT-TC-1A.

NOTE: There is RECOMMENDED READING assigned at the beginning of the course. The completion of these assignments in addition to self-study is strongly encouraged and will add to the overall training benefit and time to be credited. It will also better prepare the student for the practical lab/’hands-on” session. It is recommended that the student a log of the self-study time. It is also recommended that the applicable Level III be involved and confirm that the reading and self-study assignments have been completed. This should become a part of the student’s training records which may be used in conjunction with subsequent certifications.
