Mr. Mason

asked the Parliamentary Secretary for Science when Her Majesty's Government intend to introduce a national code of symbols identifying radioactive material containers so that police and firemen may quickly assess the degree of radiation danger in the event of accidents or fire.

Mr. Denzil Freeth

I have nothing to add to the reply I gave the hon. Member on 21st February last.
