and
5C.2 Has provided evidence of having:
5C.2.1 Satisfactorily completed 40 hours of training including each of the following:
(1) Fundamentals of radiation safety including:
(a) Characteristics of gamma and x-radiation;
(b) Units of radiation dose and quantity of radioactivity;
(c) Hazards of exposure to radiation;
(d) Levels of radiation from sources of radiation;
(e) Methods of controlling radiation dose (time, distance, and shielding); and
(2) Radiation detection instruments including:
(a) Use, operation, calibration, and limitations of radiation survey instruments;
(b) Survey techniques; and
(c) Use of personnel monitoring equipment; and
(3) Equipment to be used including:
(a) Operation and control of radiographic exposure equipment, remote handling equipment, and storage containers, including pictures or models of source assemblies (pigtails);
(b) Operation and control of radiation machines;
(c) Storage, control, and disposal of sources of radiation; and
(d) Inspection and maintenance of equipment; and
(4) The requirements of pertinent state and federal regulations; and
(5) Case histories of accidents in radiography; and
5C.2.2 Successfully completed a written or oral examination after having received copies of and instruction in the:
(1) Requirements of Part 5;
(2) Requirements of applicable sections of Parts 4, 10 and 17;
(3) License or registration under which the radiographer will perform industrial radiography; and
(4) Licensee's or registrant's operating and emergency procedures; and
