The risk of systemic infection is higher when the organism has a combined injury, such as a conventional blast, thermal burn, [3] or radiation burn. [2] There is a direct quantitative relationship between the magnitude of the neutropenia that develops after exposure to radiation and the increased risk of developing infection. Because no ...
Diagnosis is typically made based on a history of significant radiation exposure and suitable clinical findings. [3] An absolute lymphocyte count can give a rough estimate of radiation exposure. [3] Time from exposure to vomiting can also give estimates of exposure levels if they are less than 10 Gy (1000 rad). [3]
The lungs are a radiosensitive organ, and radiation pneumonitis can occur leading to pulmonary insufficiency and death (100% after exposure to 50 gray of radiation) in a few months. Radiation pneumonitis is characterized by: Loss of epithelial cells; Edema; Inflammation; Occlusions airways, air sacs and blood vessels; Fibrosis
The radiation which is produced by low-energy mobile radiation systems has a limited range. For this reason, conventional walls are regarded sufficient to stop the radiation scatter produced in the operating room and no extra measures for radiation protection are necessary. This makes IORT accessible for more hospitals.
The embryo and fetus are considered highly sensitive to radiation exposure. [8] Complications from radiation exposure include malformation of internal organs, reduction of IQ, and cancer formation. [8] The SI unit of exposure is the coulomb per kilogram (C/kg), which has largely replaced the roentgen (R). [9]
Radiation proctitis or radiation proctopathy is a condition characterized by damage to the rectum after exposure to x-rays or other ionizing radiation as a part of radiation therapy. [1] Radiation proctopathy may occur as acute inflammation called "acute radiation proctitis" (and the related radiation colitis) or with chronic changes ...
Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level radiation.
Ionizing radiation is generally harmful and potentially lethal to living things but can have health benefits in radiation therapy for the treatment of cancer and thyrotoxicosis. Its most common impact is the induction of cancer with a latent period of years or decades after exposure.
