We make recommendations for shielding around x-ray units, including CT. As needed, we will work with the architect to help ensure the area is designed with radiation safety in mind. Once construction is complete, we can evaluate the integrity of the shielding to verify the shielding was installed correctly, with no gaps or "holes".
We need an "architectural drawing" or the equivalent to do a shielding evaluation. The adjacent areas should be labelled so that we know what the area is used for and can plan with an "occupancy factor". We will need to know the # of x-rays or scans which will be done in the room each week.
Kansas Radiation Regulations
28-35-167. Shielding plan for radiation producing devices.
(a) Before construction, the floor plan or plans, shielding specifications, and equipment arrangement of all new installations, or modifications of existing installations, utilizing ionizing radiation machines shall be submitted to the department for review and consideration for approval, with the information specified in K.A.R. 28-35-168 and K.A.R. 28-35-169 of this part.
(b) If the applicant is not a qualified expert, then the applicant may be required to utilize the services of a qualified expert to determine the
shielding specifications before the secretary’s review and consideration for approval of the shielding plan.
(c) The approval of the shielding specifications shall not preclude the requirement of additional modifications if a subsequent analysis of operating conditions indicates the possibility that an individual could receive a dose in excess of the limits prescribed in K.A.R. 28-35-212a and K.A.R. 28-35-214a.
