radiation is generally classified as non-ionizing radiation; however, inFigure 9.5, it appears to be on the cusp of non-ionizing andionizing radiation. While most UV radiation is non-ionizing, radiation of higher frequency and higher energy is more powerful, and thus can be considered ioniz...
Depending on the frequency, electromagnetic radiation is classified as either nonionizing or ionizing. The separation between ionizing and nonionizing radiation is generally accepted to be at wavelengths around 10 nm in the far-UV region. Nonionizing radiation is a general term for the part of ...
A radioactive source that is not under regulatory control, either because it has never been under regulatory control or because it has been abandoned, lost, misplaced, stolen, or otherwise transferred without proper authorization, is considered an orphan source. Orphan sources are usually gathered as...
such as posterior fossa ependymoma, low numbers of mutations were detected, consistent with the possibility that epigenetic changes may drive tumorigenesis30. These observations suggest that cancer is not solely a consequence of DNA mutations34,35, but whether purely non-genetic reprogramming mechanisms ...
The power of scattered electrons by an atom is negatively correlated with the energy of the incident electron13. Therefore, low-acceleration-voltage electrons produce more signal upon their interaction with the cryo-EM specimen. However, low-energy electrons create severer radiation damage14, allowing...
Laypeople’s Understanding of Radioactivity and Radiation Abstract: A) It may be argued that the population should have sufficient understanding of radiation phenomena to secure individual safety as well as democratic decisions. B) To attain this, it is necessary for the communicators of radiation inf...
Earth is one of the inner planets of the Solar System, but – unlike the others – it has an oxidising atmosphere, relatively stable temperature,
The general term non-ionizing radiation is the portion of the electromagnetic spectrum where photon energies are not strong enough to break atomic bonds. This segment of the spectrum includes ultraviolet (UV) radiation, visible light, infrared radiation, radio waves, and microwaves, along with ...
As a further example of the ability of NMR to form an image of a section through the human body without the use of damaging ionizing radiation, Fig. 13a and b show whole-body scans. Figure 13a is a section through the upper chest region perpendicular to the spinal cord. The patient is...
Missions into Deep Space are planned this decade. Yet the health consequences of exposure to microgravity and galactic cosmic radiation (GCR) over years-long missions on indispensable visceral organs such as the kidney are largely unexplored. We performe
