Medical physicists and manufacturing experts explain the relationship between radiation dose and image quality. Basically, the greater the dose is the better the image. While it is still unclear, a relationship definitely exists between radiation exposure and cancer, although the rate at which radiation dose causes cancer is difficult to measure.
Though experts worldwide agree the benefits of CT technology far outweigh the risks, diagnostic imaging quality assurance teams are urged to take appropriate measures to ensure the safety of patients and staff that interact with these devices. In lieu of the recent issues surrounding accidental CT radiation overdoses, in an action supported by the AAPM, the FDA has released recommendations for imaging facilities, radiologists, and radiologic technologists to help prevent additional cases of excess exposure.
Radiation detection is not possible by human senses. Radiation detectors are instruments that can identify the presence of radiation in the environment, received by the people as exposure and internal contamination. A single radiation detector cannot detect all kinds of radiation. It is vital to monitor and control radiation before it can cause serious hazards such as cancer, tumors, or genetic disorders. Radiation detectors are necessary for organizations that have a lot of radiation exposure, and there are crucial rules that are set down by the governing bodies. The equipment become useful in places like hospitals, fire safety departments, HAZMAT teams, nuclear power and nuclear testing facilities, and x-ray departments.
One instrument that can be used to detect radiation in the environment is the radiation dosimeter. It consists of ion chambers that provide the precision dose measurements needed for absolute dose measurement integrity. This survey meter measures environmental levels of penetrating and ionizing radiation. It may be used to determine whether it is safe to enter an area and, if so, for how long. The radiation dosimeter provides comprehensive, repeatable testing for radiographic, dental, and fluoroscopic in just a few keystrokes. It is an essential tool not only for physicists and also states agencies that need to go in and test equipment.
Sharp measures have to be taken in the design, development, and characterization of a radiation dosimeter and other radiation detectors to ensure high quality and avoid health hazards to human beings.
