From F. G. GRISLEY
It is claimed that power stations using ‘clean coal’ technology are
more attractive than nuclear reactors (In Brief, 27 August).
Many years ago I read a report that the radioactivity issuing with the
flue gas from an average coal-fired power station (due to naturally occurring
potassium-40 in coal) was five times that allowed from a nuclear plant.
Is there any truth in this?
