THERMAL power plants, fertiliser firms
and other industries involved in
largescale coal combustion could be a
major source of radiological pollution.
A team of researchers from the
research and development division of
the Projects and Development India
Limited, a New Delhi-based public sector company, have called for regular
monitoring of radiological pollution in
and around such industries.
The recommendation is based on a
decade-long investigation on the
extent of radiological pollution created
by the burning of coal in the steam and
power generation units at a fertiliser
plant at Sindri in Bihar.
The level of radioactivity released
and its exposure to the population
through the flyash produced daily was
found to be well within the maximum
permissible limit as recommended by
the International Commission for
Radiological Protection. But the finding
was based on certain assumptions that
were made for the practical purpose of
the study. So the exposure might be
higher in different conditions.
