RESUMO
Washington, J. S., Dick, J. A., Jacobsen, M., and Prentice, W. M. (1973).British Journal of Industrial Medicine,30, 365-374. A comparison of conventional and grid techniques for chest radiography in field surveys. The effect on the quality of chest radiographs using a reciprocating grid with a moderately high kilovoltage (96 to 105 kV) has been studied. A total of 1 710 mineworkers had two postero-anterior chest radiographs taken at the same visit to a linked pair of mobile ϰ-ray units. One film was taken with conventional exposure factors and the other with moderately high kilovoltage and a reciprocating grid. The grid was exchanged between the two units according to a randomized plan so that the first radiograph was not always taken with the same technique.
