Some radiological, structural, and physical properties of a clinical X-ray unit oil
1Department of Physics and Astronomy, McMaster University, Hamilton, ON L8S 48S, Canada.
Abstract:
Radiological, structural, and physical properties of an x-ray oil which absorbed a photon dose of approximately 2.0 ± 0.2 Gy during its operational life (∼10 years), were investigated. An attenuation coefficient of 0.198 ± 0.003 cm-1 (at 122 keV) was obtained. NMR, ESR, and FTIR spectroscopy suggest a preponderance of pentane, and hexane. Mass spectrometry detected tertrapentacontane, nonadecane, and docosane. No gamma-emitters were revealed with gamma spectroscopy. A boiling temperature of approximately 300 °C was measured. Microscopy revealed the presence of gas bubbles.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...
Imaging Studies I: CT and MRI
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
