Effect the Radiation Ionization on Workers in Gamma Knife

Abstract

The trigeminal nerve (the fifth cranial nerve) is the largest one between the cranial nerves and contains both sensory and motor fibers. The sensory fibers contain the General Somatic Afferent (GSA), and its function is general sensation. The motor fibers contain Special Visceral Efferent (SVE), its function is branchial arch striated muscles. To assess the efficiency of gamma knife treatment outcome of  Iraqi patients who are suffering from primary  TN (Trigeminal Nerve) and irradiated with a dose of 80 Gy and/or 89 Gy (recommended by gamma knife society with a dose range of 80-125 Gy ), and to evaluate the change in nerve thickness. Gamma rays are considered to be the most dangerous radiation in the electromagnetic field, since they possess the highest energy because of their high frequency. As for their uses, they are used in the medical and industrial fields, but in very small quantities. The doses of radiation given to the patient are calculated so accurately that they destroy the cancer cells. The healthy body cells regain their health after recovery and can follow the course of the body's vital processes. Also here in the project we have worked on measurements of the effect of radiation on the workers in this area where there is no effect on the workers outside the room when the device is operating and give radiation to the patient because the room is completely isolated from the arrival of any radioactive effects harmful to workers.
