Medical physicists (MP) may count the time they spent in the actual performance of surveys towards satisfying the survey contact hour training requirement. As guidance, however, FDA recommends that MPs not count more than four hours for each facility survey and two hours for each unit survey toward the required total hours of training. Once an MP completes the facility and unit surveys, the MP is qualified to perform screen film surveys independently but not necessarily FFDM surveys. In order for the MP to also perform FFDM surveys independently, the training program or trainer will have to supply the MP with additional documentation showing that at least eight hours of experience/training was in FFDM. 900.12(a)(3)(iii)(C).
