Disadvantages include the need for sedation, exposure to ionizing radiation, and the need to transport the patient to the scanner.
Sensors of ionizing radiation effects on the immunological microenvironment of cancer.
The accelerated electrons chaotically oscillate between the cavity walls, ionizing the working gas until they are thermalized or get on the discharge anode.
These clouds are partially ionized by nearby ionizing sources.
The stored energy is expanded principally in transferring kinetic energy to the electrons and in ionizing and exciting atoms and molecules of the gas.
The lack of ionizing radiation and side-effects mean that examination times are not restricted.
Mars surface ionizing radiation environment: need for validation.
In contrast, whilst crossover frequencies are unaffected, both pre-meiotic and meiotic exposure to ionizing radiation results in a dramatic increase in minisatellite mutation rates.
