Radiation Exposure Dosage Chart: This chart lists ionizing radiation only. Of all the types of non-ionizing radiation, only ultraviolet rays are cancer-causing agents. 10,000 mSv (1,000,000 mrem) as a short-term and whole-body dose would cause immediate illness and subsequent death within...
When these data sheets were incomplete, an electronic chart review was performed. Results: From this retrospective database of 1071 records, a total of 969 procedures were suitable for analysis in the final model. The average fluoroscopy time (95% Confidence Interval) was 4.66 (4.38 - 4.93) ...
Our objectives were to determine how many patients received more than ten CT scans in an academic emergency department (ED) over the course of 7聽years and to quantify their radiation exposure and lifetime attributable risk of cancer. An electronic chart review was performed at our urban ...
Radiation effect refers to the impact or consequences that occur following exposure to radiation, which can include ionization of atoms and molecules, leading to potential biological damage.

radiation myelopathy (redirected fromradiation myelitis) ra·di·a·tion my·e·lop·a·thy damage to a portion of the spinal cord from exposure to x-rays or other high-energy radiation; most often affects the cervical segments; depending on their time of onset and persistence, two forms are...
t increase health risks, there is concern about their effects over time. W. Kent Tobiska, the president of Space Environment Technologies in Los Angeles and lead author of the paper, thinks that in the coming years, the US will develop standards for radiation exposure for travelers to keep ...

The purpose of this study was to examine the relationship between radiation exposure and subsequent development of salivary gland tumors (SGTs). Eighteen patients with SGTs as second cancers after head and neck irradiation were identified from chart review of institutional databases of 3025 patients ...
For a sinewave object (rather than a bar or squarewave resolution chart), the system MTF can be shown to be equal to the system modulation contrast function (MCF), which is the ratio of image-plane modulation contrast to object-plane modulation contrast. Modulation contrast in each plane is...
