(80 hour/10 day Course)

This Level I/II course satisfies the syllabus requirements of ASNT-CP-189, SNT-TC-1A, NAS 410, BS EN 4179 and PCN. It is suitable for engineering inspectors at all levels of experience who require formal training and a qualification in this subject.

The training programme covers 50% theory and 50% practical application allowing the student time to obtain a good foundation in this method of NDT by practicing a large variety of inspection techniques under the supervision of qualified instructors. The course covers both X and Gamma Radiography using a purpose built exposure room and the latest up to date Radiographic equipment.

The course comprises:
Explanation of training school safety procedures.
Use of film badges/TLD’s and doserate meters.
Dose limits – properties of radiation.
Radiographic principles – radiation sources.
Types, structure and methods of packing industrial x-ray film.
Study of darkroom procedures including checking equipment.
Purpose and use of individual chemicals.
Maintenance and replenishment of chemicals.
Methods of manual and automatic processing.
Identification of handling and processing faults.
Production and uses of film characteristic curves and exposure charts.
Calculation of exposure and correction procedures.
Study of x-ray production and construction of various types of equipment.
Factors that affect both exposure and sensitivity.
Physiological effects of radiation together with safety procedures.
Practical radiography.
Radioactive Isotopes.
Safety of operation and calculations for exposure.
Preparation of technique and report writing procedures.
Radiographic film interpretation.

All students are continuously assessed during the course by homework and progress tests together with a theoretical and practical end of course examination.

At the end of the course the students can also take approval examinations in Radiographic Inspection at Level I, II or Level III to SNT-TC-1A, NAS 410 or BS EN 4179 in accordance with their company written practice.

International School of Aerospace NDT also acts as an outside agency providing Level III services as defined in the aforementioned documents.
