One of the best treatment methods for many types of cancer is done through radiotherapy. If radiation doses are too small, it could mean treatment could be ineffective but on the other hand, if the treatment is given too large than treatment can be very harmful as well. It is important for a specialist to calculate and use accurate doses of radiation on each patient for proper effectiveness and above all the patient’s safety. Dosimetry is the science of measuring and assessing the dose of radiation that is absorbed during treatment. Each clinic needs to have reliable radiation equipment that is carefully and continuously calibrated for each patient’s service to be performed.
