These days dust free enclosed shotblasting can be carried out with an absolute minimum of disturbance. We have worked in some very stringent and controlled areas; hospitals, bakeries and pharmaceutical areas are good examples. One of the more demanding areas of work recently was within a nuclear power station where work was carried out adjacent to the reactor itself.
The work was quite straightforward but the controls were quite rigid. All equipment and materials, as well as the men doing the work, had to be monitored all the time and decontaminated on completion of works and before removal from the site. It is reassuring to know that the nuclear industry takes such care with health and safety.
After two weeks in use the equipment showed less radiation that you would receive on a three hour flight to Spain.
