asked Her Majesty's Government:Whether they will circulate, to officials of the Department of Health and Social Security, pneumoconiosis medical panels and members of industrial tribunals, a note summarising the scientific evidence which shows that there is no safe lower limit of exposure to asbestos.

We are satisfied that evidence as to safe limits of exposure to asbestos is already available to members of the pneumoconiosis medical panels, the medical appeal tribunals and those officials of the Department of Health and Social Security concerned with such matters.
