Abstract:

This apparatus is not in contact with the pavement, but measures the gamma radiation re-emitted by the material. The small telecontrolled from a tender. The use of radioactive material in an outdoor environment with traffic on nearby lanes and construction plant and labour in the vicinity required reliable safety procedures. Infra red provides a suitable communication link. The tender driver can control the truck's distance upto a distance of 50m. Capacity is 2km in four hours, The flexibility of the apparatus and its on-site data processing capability make it ideal for quik controls on disseminated jobsites
