3. In regulation 2(1) (interpretation), after the definition of “intense sweetener”, there shall be inserted the following definitions:
““ionising radiation” means any gamma rays, x-rays or corpuscular radiations which are capable of producing ions either directly or indirectly other than those rays or radiations—
which are emitted by measuring or inspection devices,
which are emitted at an energy level no higher than the appropriate maximum level, and
the dose of energy imparted by which does not exceed 0.5Gy,
and for the purposes of this definition the appropriate maximum level is 10 MeV in the case of x-rays and 5 MeV otherwise;
“irradiated” means subjected to treatment by ionising radiation;”.
