Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, and skin wound infections.
Radioactive label on containers aboard a US Navy ship. Any quantity of packages bearing the RADIOACTIVE YELLOW III label (LSA-III). Some radioactive materials in "exclusive use" with low specific activity radioactive materials will not bear the label, however, the RADIOACTIVE placard is required.
The overall process of using a radioactive material to excite a phosphor and ultimately generate light is called radioluminescence. As tritium illumination requires no electrical energy, it has found wide use in applications such as emergency exit signs , illumination of wristwatches, and portable yet very reliable sources of low intensity ...
The 131 I isotope is also used as a radioactive label for certain radiopharmaceuticals that can be used for therapy, e.g. 131 I-metaiodobenzylguanidine (131 I-MIBG) for imaging and treating pheochromocytoma and neuroblastoma. In all of these therapeutic uses, 131 I destroys tissue by short-range beta radiation. About 90% of its radiation damage ...
The particle usually comes from the radioactive decay of an atom of a radioisotope, an isotope of an element which is radioactive. The electron then returns to its ground energy level by emitting the extra energy as a photon of light. A chemical that releases light of a particular color when struck by ionizing radiation is called a phosphor ...
Contour Glove. From the brand behind the T&C-loved red light therapy face mask, this FDA-cleared device comes in the form of a glove to improve the appearance of sunspots, dryness, pigmentation ...
In the end, McDaniel summed up the experience with the same warmth and wisdom that resonated in the video: “I don’t think there’s a cap on believing in good things or magic in the world.
If good health physics controls are maintained in a laboratory where radionuclides are used, it is unlikely that the overall radiation dose received by workers will be of much significance. Nevertheless, the effects of low doses are mostly unknown so many regulations exist to avoid unnecessary risks, such as skin or internal exposure.
