The use of radioactive sources in hospitals requires many safety measures to be implemented to ensure that workers and the general public are protected. Although there are a number of measures such as shielding, dose rate and contamination monitoring and personal dosimetry that can be used to record radiation exposure, a key method of ensuring the safety of nurses, doctors and patients, is the use of fixed area radiation monitors. Fixed area monitors use multiple detectors to provide the dose rate levels of iodine therapy centres, patient treatment rooms and nuclear medicine departments. Critical and potentially life saving information is provided as fixed area monitors incorporate 24/7 monitoring with an early warning alarm that inform patients and staff when dose rates exceed set alarm thresholds. This ensures that all radiation risks are managed safely which is key to safer working practices for all personnel working within a medical environment.
