(b) The survey shall be performed by, or under the direction of, an authorized medical physicist or radiation safety officer who shall determine and record whether radiation levels are in compliance with the dose limits of Part III of Chapter 64E-5, F.A.C. Portable shielding may be used to comply with these radiation dose limits. Such surveys shall be conducted with the electronic brachytherapy device controls, source position, portable shielding and site-specific scattering phantom all set so as to produce the highest radiation exposure level that could occur during treatment.

(c) The survey record shall include: the date of the measurements; the reason the survey is required; the manufacturer's name, model number and serial number of the electronic brachytherapy device; the instrument(s) used to measure radiation levels; a plan of the areas surrounding the treatment room that were surveyed; the measured dose rate at several points in each area expressed in microsieverts or millirems per hour; the calculated maximum level of radiation over a period of 1 week for each restricted and unrestricted area; and the signature of the individual responsible for conducting the survey.

(d) A survey shall also be performed prior to any subsequent medical use, when:
1. Making any change in the portable shielding,
