A few pointers to be kept in mind in our daily use of the x-ray are as follows, in order to avoid unnecessary exposure.
GENERAL:
-Choose the technique well and execute it properly.
-Adequate filtration and collimation techniques to be used
-Adjust KVP to optimum, since low KVP leads to more absorption of hazardous rays.
-Reduce exposure time and adopt using hi-speed films.
-Check for leakage from machine, also avoid keeping the machine switched on when not in use.
-Follow processing steps meticulously with timely replenishing the solutions to get good results and to prevent repetition of xrays.
PROTECTION OF OPERATOR:
-Do not hold the film in patients mouth, train patient to do so as well as follow usage of film holders.
-Stand 6feet away from the tube.
-Use lead barrier/apron.
-Periodic and continuous determination of radiation rate received by the personnel by using personal monitors such as pocket dosimeter, film badge, thermo luminiscent dosimeter.
