3 Credit Hours
Student Level:
This course is open to students on the college level in either the freshman or sophomore year and to high school vocational students.
Catalog Description:
NDT3464 - Radiographic Testing I (3 hrs.)
This course is devised to give an introductory study of the processes of radiography. It provides the in-depth study and hands-on experience needed to prepare the student for a position in the field of radiography. The course is designed to meet certain NDT Level II requirements in accordance with A.S.N.T., SNT-TC-1A, and NAS-410.
Course Classification:
Lab
Prerequisites:
INR3716 Technical Mathematics, NDT3451 Introduction to NDT, or instructor approval.
Controlling Purpose:
This course is designed to impart the fundamentals of radiographic testing; it’s applications, techniques, process controls and the terminology, such that the student could pass a typical industrial certification examination in accordance with A.S.N.T., SNT-TC-1A, or NAS-410.
Learner Outcomes:
Upon completion of this course the student will be able to:
- Perform and interpret standard process control tests.
- List and describe differences between the specific processes.
- Explain test requirements for a specific component from a given specification.
- Perform given radiographic inspection correctly and to interpret and report the results.
- Take and pass a qualification examination (theory and practical prepared in accordance with the industry standards SNT-TC-1A or NAS-410.
- Correctly apply all safety attitudes and procedures associated with radiographic testing that will insure a safe work place environment.
- Understand and perform the duties of a Level I Radiographer.

UNIT 6: Imaging and Film
Outcomes: Upon completion of this unit, the students will be able to successfully explain the processes of imaging and film selection.
- Explain the terms: latitude, contrast, speed, scatter, grain size, as they apply to industrial radiographic film.
- List and compare five films from different manufactures. Explain why some require less time to expose than others
- Using the curves of six films, calculate density changes.
- Create an exposure chart and demonstrate the accuracy of the chart.
UNIT 7: Processing Radiographs
Outcomes: Upon completion of this unit, the students will be able to successfully process a radiograph.
- Apply classroom training and demonstrations to process a radiograph using standard practice techniques when manually processed.
- Explain the developing process when the film is placed in the developer.

Attendance Policy:
Students should adhere to the attendance policy outlined by the instructor in the course syllabus.
Grading Policy:
The grading policy will be outlined by the instructor in the course syllabus.
Maximum class size:
Based on classroom occupancy.
Course Time Frame:
The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college. A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time. The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
