Background of the Study
Protecting the patient from unnecessary radiation exposure include not only the Cardinal Principles of radiation protection, but also the behaviors of imaging personnel towards each patient. It is often asked, "Why do we need to discuss patient protection when it is the patient who is being imaged and therefore being exposed to radiation?" "And is not all radiation exposure made within safe limits so that patient protection is not really possible?" The answer centers on the concept of ALARA, which is the basic principle of radiation protection. Again, the operator of any medical imaging radiographic equipment is mandated to use as low as is reasonably achievable radiation dose to provide the highest quality radiographic image. Any unsafe exposure beyond the ALARA principle is considered unnecessary excess exposure. Not just anyone can be a satisfactory substitute to advocate patient radiation protection through equipment operation in the place of an educated imaging professional. Though radiographers are not the exclusive gatekeepers to thousands of rads of radiation dosed upon a trusting public annually, they are the educated professionals who practice daily safe exposure principles. Practicing ALARA as a form of patient radiation safety while providing diagnostic information for radiological interpretation is the focus of this issue. We will look at how radiographers make the most of the Cardinal rules of time, distance, and shielding as part of the ALARA mandate to protect patients from unnecessary radiation exposure. These principles are part of the continuum of competent imaging and positioning skills to bring about radiation safety for patients and personnel. This research paper discusses what measures are employed to assure ALARA while providing diagnostic images for radiological interpretation, and discusses how the radiographer controls various aspects of technique selection to augment the ALARA principle.

The foundation of the radiography profession is the production of quality radiographic images, and its pillars are personal and patient radiation safety practices. Understanding the principles of source and electromagnetic radiation, and exposure techniques are fundamental to the radiographers' profession. Suffice it to say, radiographers manage radiation so that patient exposure is considered exceptionally safe and occupational risk is the same as for most safe professions.

In this age of technology many things are rapidly changing in the imaging discipline; however, the physical concepts of radiation exposure to produce diagnostic quality images remain a fundamental part of the imaging discipline. In addition, the x-ray tube apparatus design is engineered with patient protection as one of its highest standards. Likewise, the radiographer's selection of radiographic techniques encompasses the highest radiation protection standards possible. Principles of patient radiation exposure that minimize unnecessary exposure and accent imaging benefits are cornerstone principles of our profession. In this research, we will discuss the benefits of beam filtration, mAs and kVp selection, positive beam limitation, automatic exposure control, beam restriction, and shielding as means to apply the cardinal rules of radiation protection to the patient and to attain ALARA.

The basic question that this study addresses is how strict the implementation of radiation protection principles is and how effective are those radiation protection practices in reducing the risk of patients from unnecessary exposures to radiation. Statement of the problem
