WebA radiation protection survey must be completed before operation to ensure that the structural shielding is adequate to meet the requirements of Sections 16.6 and 16.7. Scan protocols Each CT unit shall have posted scan protocols available for reference by the operator. As a minimum, these protocols shall be include the following scan factors ... WebThe guiding principle of radiation safety is “ALARA”. ALARA stands for “as low as reasonably achievable”. ALARA means avoiding exposure to radiation that does not have a direct benefit to you, even if the dose is small. To do this, you can use three basic protective measures in radiation safety: time, distance, and shielding.
