Section He-P 4047.05 - General Technical Requirements for Facilities Using Therapeutic Radiation Machines

(a) The registrant shall ensure that radiation protection surveys of all new facilities, and existing facilities not previously surveyed, are performed with an operable radiation measurement survey instrument calibrated in accordance with He-P 4047.08.

(b) The radiation protection survey shall be performed by, or under the direction of, a radiation therapy physicist or a qualified expert.

(c) The radiation protection survey shall verify that, with the therapeutic radiation machine in a "BEAM-ON" condition, with the largest clinically available treatment field and with a scattering phantom in the useful beam of radiation, the following requirements are met:

(1) Radiation levels in restricted areas are not likely to cause personnel exposures in excess of the limits specified in He-P 4020.05; and

(2) Radiation levels in unrestricted areas do not exceed the limits specified in He-P 4020.13(a) and (b) .

(d) In addition to the requirements of He-P 4047.05(a) , a radiation protection survey shall also be performed prior to any subsequent medical use; and:

(1) After making any change in the treatment room shielding;

(2) After making any change in the location of the therapeutic radiation machine within the treatment room;

(3) After relocating the therapeutic radiation machine to a different treatment room; or

(4) Before using the therapeutic radiation machine in a manner that could result in increased radiation levels in areas outside the external radiation therapy treatment room.

(e) The survey record required in He-P 4047.05(d) shall include:

(1) All instances where the facility is in violation of applicable rules;

(2) The date of the measurements;

(f) If the results of the surveys required by He-P 4047.05(a) and (d) indicate any radiation levels in excess of the respective limit specified in He-P 4020, the registrant shall lock the control in the "OFF" position and not use the unit except as may be necessary to repair, replace, or test the therapeutic radiation machine, test the therapeutic radiation machine shielding, or test the treatment room shielding.

(g) If the survey required by He-P 4047.05(a) and (d) indicates that an individual in an unrestricted area may be exposed to levels of radiation greater than those permitted by He-P 4020.13(a) and (b) , before beginning the treatment program the registrant shall:

(1) Equip the unit with beam direction interlocks or add additional radiation shielding to ensure compliance with He-P 4020.13(a) and (b) ;
