      As radiography is increased these days, we cannot but consider the exposure on radiation seriously, which is the responsibility of radiotechnologists for people's health. The following are the factors decreasing the dose of exposure as far as there is no loss in the quality of image :
      1. A suitable filter plate can remove the electromagnetic wave which has low energy and which isn't needed in image.
      2. The improvement and the proper use of a collimator can decrease the area exposed on radiation.
      3. The proper combination of high-quality-film and screen can increase the degree of sensitivity.
      4. The high-light fluorescent plate and the fluorescent-image intensifier tube reduce the dose of fluoroscopy.
      5. High-voltage radiography reduces the dose of exposure and fluoroscopy.
      6. The improvement of developing method can increase the sensitivity and decrease exposure.
      7. The operations of Auto-exposure and CR prevent the failure and the repeat of radiography.
      8. The appliance preventing radiation reduces the size of exposed field.
      9. The Grid should be selected properly in accordance with tube voltage.
      10. The invention and the improvement of radiographic devices can reduce the dose of exposure.
