disposal of radio-active waste is strictly
controlled. There are limits to the amounts which
can be disposed of to sewers and which can be
incinerated during any monthly period and they
must be adhered to. Records must be kept of all

month and a running total must be recorded in the
log book (Refer to local rules). The Controlled
