AB KEY  POINTSImportant  concepts  used  to  describe  radiation  include  exposure,  absorbed  dose,  and  dose  equivalent.A  relatable  way  of  explaining  the  radiation  dose  from  medical  procedures  to  patients  is  to  compare  the  dose  to  the  reference  dose,  the  yearly  radiation  exposure  from  natural  sources.Institutions  must  maintain  radiation  levels  consistent  with  the  As  Low  As  Reasonably  Achievable  (ALARA)  philosophy.Deleterious  effects  of  radiation  are  classified  as  either  stochastic,  where  the  probability  of  occurrence  increases  with  dose,  or  deterministic,  in  which  the  severity  increases  with  dose  after  a  threshold  is  exceeded.Major  factors  in  limiting  dose  are  time,  distance,  and  shielding.Regulatory  agencies,  such  as  the  Nuclear  Regulatory  Commission  (or  state  agencies  in  Agreement  States),  regulate  the  use  of  radioactive  materials  including  transportation,  handling,  disposal,  personnel  monitoring,  and  medical  use.
