NDT 3466 RADIOGRAPHIC TESTING III
3 Credit Hours
This course is open to students on the college level in either the freshman or sophomore year and to high school vocational students.
NDT 3466 - Radiographic Testing III (3 hrs.)
This course is devised to provide an in-depth study of the processes of radiography. It provides hands-on experience to prepare the student for a position in the field of radiography.
NDT3465 Radiographic Testing II or instructor approval.
This course is designed to impart advanced applied radiographic practical applications, techniques, so the student could perform, develop, and interpret radiographs.
Upon completion of this course the student will be able to:
- Demonstrate calculations for density changes.
- Demonstrate image quality using screens, filters, and IQI’s.
- Calculate and demonstrate choices of film, density, and sensitivity per AWS code.
- Calculate and demonstrate choices of film, density, and sensitivity per API code.
- Calculate and demonstrate choices of film, speed, density, per ASME code.
- Demonstrate the ability to maintain records.
- Demonstrate ability to interpret film images on radiographs.
- Correctly apply all safety attitudes and procedures associated with radiographic testing.
- Apply his or her knowledge, by performing practical applications similar to those performed by radiographer.
Unit Outcomes for Criterion Based Evaluation:
The following outline defines the minimum core content not including the final examination period. Instructors may add other material as time allows.
UNIT 1: DENSITY CHANGES
Outcomes: Upon completion of this unit, the students will be able to successfully make calculations to change density of a radiograph.
- Given five radiographs, correctly predict the change of density when exposed at a new time, or ma setting.
- Given five radiographs, correctly predict the change of density when exposed to a film of a different speed.
- Given five radiographs, correctly predict the change of density when exposed to a film from a different manufacturer.
UNIT 2: SCREENS AND FILTERS
Outcomes: Upon completion of this unit, the students will be able to successfully perform radiography, using screens filters, verifying using IQI’s.
- Apply knowledge of screens to produce five radiographs with reduced x-ray scatter.
- Demonstrate the use of copper filters placed near the tube port on three radiograph images.
- List and explain how application of differing kV affects the outcome of a radiograph when using lead screens.
UNIT 3: RADIOGRAPHIC IMAGE QUALITY
Outcomes: upon completion of this unit, the students will be able to successfully produce radiographs with image quality equal to or exceeding code requirements with image quality equal to or exceeding code requirements.
- Determine image quality requirements of API 1104, and produce five radiographs exceeding the requirements.
- Determine image quality requirements of ASME Section V produce five radiographs exceeding the requirement.
- Determine image quality requirements of the D1.1 and D17.1. codes and produce five radiographs exceeding the requirements.
- Given an exposure chart, make changes in distance while maintaining density.
- Given an exposure chart for steel, produce three radiographs of aluminum using correction factors.
- Double load a cassette and meet image requirements for varying thickness of material with one exposure.
UNIT 4: FILM HANDLING, LOADING AND PROCESSING
Outcomes: Upon completion of this unit, the student will be able to successfully process film manually and automatically.
- Correctly maintain density check log for manual and automatic processing units.
- Correctly mix chemicals, and apply process control checks for manual processing of film.
- Correctly mix chemicals, and apply process control checks in automatic processing unit.
- Correctly maintain quality checks of the densitometer, film viewers, and the viewing room.
UNIT 5: X-RAY RECORDS
Outcomes: Upon completion of this unit, the students will be able to successfully maintain records for safety, reporting, cabinet use, and process controls.
- Record and enter all film exposures in the exposure log.
- Record and enter dosimeter readings in the daily log.
- Record and enter records for TLD’s.
- Record and enter all information of fifteen radiography report sheets, as required by codes.
- Record and enter all information on cabinet leakage as required by the State of Kansas.
UNIT 6: RADIOGRAPHIC VIEWING
Outcomes: Upon completion of this unit, the students will be able to successfully interpret films as required by code.
- Interpret twenty films per AWS D1.1 and AWS D17.1 with 80% accuracy.
- Interpret twenty films per API 1104 with 80% accuracy.
- Interpret twenty films per ASME Section VIII with 80% accuracy.
- Complete computer film interpretation program 80% or greater accuracy.

Students should adhere to the attendance policy outlined by the instructor in the course syllabus.
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.
