Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
The Gamma variant (P.1) [a] was [6] [7] one of the variants of SARS-CoV-2, the virus that causes COVID-19. [8] This variant of SARS-CoV-2 has been named lineage P.1 and has 17 amino acid substitutions , ten of which in its spike protein, including these three designated to be of particular concern: N501Y , E484K and K417T.
A study of samples collected in Manaus between November 2020 and January 2021, indicated that the Gamma variant is 1.4–2.2 times more transmissible and was shown to be capable of evading 25–61% of inherited immunity from previous coronavirus diseases, leading to the possibility of reinfection after recovery from an earlier COVID-19 ...
COVID-19 is the deadliest pandemic in US history; [360] it was the third-leading cause of death in the US in 2020, behind heart disease and cancer.

Exposing skin to infrared radiation near visible light (IR-A) leads to increased production of free radicals. [41] Short-term exposure can be beneficial (activating protective responses), while prolonged exposure can lead to photoaging. [42] Another important factor is the distance between the worker and the source of radiation.
