Characteristics Performance of Newly Developed Parallel Plate Chamber in Electron Beams.

Background: To investigate the dosimetric performance of newly developed parallel plate chamber in electron beams.

Materials And Methods: Rosalina Instruments India Private Limited (Mumbai, Maharashtra, India) has designed and fabricated PRATT2 parallel plate chamber. The various dosimetric characteristics, including pre- and post-irradiation leakage, stability, polarity effect, chamber response with bias voltage, dose linearity, dose rate effect, and chamber absorbed dose calibration, were performed for the developed chamber.

Dosimetric evaluation of newly developed well-type ionization chamber for use in the calibration of brachytherapy sources.

The well-type ionization chamber has been designed for convenient use in brachytherapy source strength calibration. The chamber has a volume of 240 cm, weight of 2.5 kg, and is open to atmospheric conditions.

Dosimetric Performance of Newly Developed Farmer-Type Ionization Chamber in Radiotherapy Practice.

Dose measurement with ionization chamber is essential to deliver accurate dose to the tumor in radiotherapy. The cylindrical Farmer-type ionization chamber is recommended by various dosimetry protocols for dose measurement of radiotherapy beams. The air-equivalent graphite wall Farmer-type ionization chamber (FAR 65 GB) of active volume 0.
