South Australian Consolidated Regulations South Australian Consolidated Regulations129—Storage of sealed radioactive sources and unsealed radioactive
substances
A person who owns a sealed radioactive source or is the registered occupier of
any premises in which an unsealed radioactive substance is stored, being a
source or substance that is not being handled or used, must—
(a)
store the source or substance so that—
(i)
the equivalent dose rate in any area accessible to
members of the public and outside the place of storage is as low as is
reasonably achievable and in no case exceeds 25 microsievert per hour; and
(ii)
no person receives an effective dose exceeding the
appropriate dose limit referred to in Part 2 Division 2; and
(iii)
the place of storage is ventilated in such a way that the
concentration of airborne radioactive substances within the place of storage
will, for any period of time that the place of storage is occupied, be as low
as is reasonably achievable; and
(b) take
reasonable precautions to prevent unauthorised access to the source or
substance or unauthorised removal of the source or substance from the place of
storage; and
(c) if
it is reasonably foreseeable that, during a period of time, chemical,
radiation or other action may weaken or rupture a container in which the
source or substance is stored so as to cause leakage from that
container—provide suitable secondary containment adequate to contain the
entire quantity of radioactive substance.
