( Introuction
(.( Purpose
This %pecification describes !DO"s requirements for managing radioactive materials andgenerators of ionising radiation to protect people and the environment from harmful effects ofionising radiation.
(.) Scope
This %pecification applies to all !DO( 4ontractor and %ub-4ontractor activities involvingionising radiation and outlines the requirements to be fulfilled.
The %pecification does not apply to non-ionising radiation such as microwave(radiofrequency( ultraviolet( visible light and infrared radiation.
This %pecification does not address Naturally Occurring *adioactive $aterials @NO*$Bwhich is covered in %!-,,/( 7%# %pecification - $anagement of Naturally Occurring
*adioactive $aterials.
(.* Definitions
%ources of ionising radiation used within !DO can be divided into:
,. Seale sources4hemical sources emitting gamma rays and2or neutrons @Used in welllogging( fluid density( phase and thic'ness measurements and industrial radiographyB.
+. $nseale sources *adioactive tracers @used in production flow investigationsB.. 9enerators G-ray equipment such as those used in production chemical @G-ray
fluorescence G*)B( industrial radiography and medical imaging and miniature particleaccelerators @$initronB emitting high energy neutrons @used in well loggingB.
Ionising Raiation: *adiation that produces ionisation in matter. #;amples are alphaparticles( beta particles( gamma-rays( G-rays and neutrons( often denoted by I( J-( K( G- andn-radiation respectively.
Raioactive materialsare defined in Oman as any material with an activity concentrationgreater than , '&q2'g @, &q2gB.
Classifie Raiological 8or5er0ndividuals who through the course of their wor' are li'elyto receive an annual dose equal or greater than + m%v2year. !ersonal monitoring andmedical surveillance are mandatory for radiological wor'ers.

Supervise 0rea n area where the immediate dose rate e;ceeds +.C L%v2h but does not
e;ceed /.C L%v2h.
Seale Source radioactive substance sealed in a container which has sufficientmechanical strength to prevent contact with and dispersion of the radioactive material underthe conditions of use and wear for which it was designed.

*adioactive waste differs from all other types of waste. 0ts radioactivity decreases only with
time( and its radioactive properties cannot be altered or destroyed by any physical( chemicalor biological treatment.
%ealed sources and tracer applications account for most of the industrial use of radioactivesubstances. There is almost no waste disposal required in the use of sealed sources( e;ceptfor disposal of the source upon decay of its radioactivity to levels at which it can no longer beused. Damage to the sealed source may result in radioactive waste in the form ofcontaminated equipment( pac'ing( clothing and other accessories.
