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 highe
Non-ionizing radiation (NIR) is the part of the electromagnetic field (EMF) spectrum covering static electric and magnetic fields, low-frequency electric and magnetic fields, radiofrequency (RF) EMFs, and microwaves, including optical radiation such as infrared and visible light. Its name derives ...
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 ...
Earth is one of the inner planets of the Solar System, but – unlike the others – it has an oxidising atmosphere, relatively stable temperature,
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...
Ionizing radiation absorbed by patient during one scan is up to 15 mSv, what is one third of allowed exposition for workers with ionizing source per year and for common people exceeds allowed hygiene limits even 15 times (Statni urad pro jadernou bezpecnost2002). For this reason, use of ...
One example of biological manufacturing of terpenoids is the production of the anti-malarial drug artemisinin precursor, artemisinic acid, using recombinant enzymes in microbial platforms [7, 8]. Artemisinin is a sesquiterpene lactone endoperoxide extracted from the medicinal plant, sweet wormwood (...
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 ...
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 ...
