HC Deb 23 February 1993 vol 219 c519W
Mr. John Marshall

To ask the Secretary of State for the Environment what the alpha discharges were from the B204 stack at Sellafield for the last five years.

Mr. Maclean

Using the latest calibration factors the alpha releases from the B204 stack and for comparison the total for all schedule 1 stacks were:

B204 stack All schedule 1 slacks
MBq MBq
11992 113 169
1991 158 274
1990 193 263
1989 262 338
1988 376 459
1 The 1992 figures do not yet include the December returns.

The present annual limit for all schedule 1 stacks is 4,300 MBq.

These should be compared with the range in my answer to the right hon. Member for Copeland (Dr. Cunningham), on 15 February, at column 21.
