WHAT ARE THE MAJOR RADIATION PROTECTION PRINCIPLES? There are three major principles that assist in maintaining ALARA and can help prevent both unnecessary exposure and overexposure. ALARA – As Low As Reasonably Achievable means means making every reasonable effort to 14 w w w . s h e n a . g o v . b n maintain exposures to ionizing radiation as far below the dose limits as practical.
