TI  - Modified ferrous ammonium sulfate benzoic acid xyelenol orange (MFBX) and 
      thermoluminescent dosimeters--a comparative study.
PG  - N153-8
AB  - Radiation dosimetry deals with the determination of absorbed dose to the medium 
      exposed to ionizing radiation. Chemical dosimetry depends on oxidation or 
      reduction of chemicals by ionizing radiation. A ferrous ammonium sulfate benzoic 
      acid xyelenol orange (FBX) dosimeter based on this principle is being used as a 
      clinical dosimeter at present. Certain modifications were carried out in the 
      preparation and storage of the FBX dosimeter to increase its shelf life. The 
      resulting dosimeter was called a modified FBX (MFBX) dosimeter and has been used 
      in our department for the past few years. An extensive study of the dose, dose 
      rate and energy response of the dosimeter was carried out and compared with a 
      thermoluminescent (LiF7) dosimeter. The results obtained were found to be 
      comparable to the thermoluminescent (LiF7) dosimeter. Hence it was concluded that 
      the MFBX dosimeter could be used for phantom dosimetry, data collection and in 
      vivo measurements. Easier preparation and availability of the reagents are added 
      advantages of using MFBX as a clinical dosimeter in small radiotherapy 
      departments.
