Sv
Sv, also known as Sievert, is a unit of measurement used in radiation protection to quantify the amount of radiation absorbed by human tissue. It is named after Rolf Maximilian Sievert, a Swedish medical physicist who made significant contributions to the field of radiation protection. The Sv unit takes into account the type of radiation and the sensitivity of the tissue being exposed to it, allowing for a more accurate assessment of the potential harm caused by radiation exposure. The Sv unit is commonly used in the medical field to measure the radiation dose received by patients during diagnostic imaging procedures such as X-rays, CT scans, and nuclear medicine scans. It is also used in the industrial sector to measure the radiation exposure of workers in nuclear power plants, nuclear waste management facilities, and other industries that involve the use of radioactive materials. One Sv is equivalent to one joule of energy absorbed per kilogram of tissue. However, the amount of radiation that is considered safe for human exposure varies depending on the type of radiation and the sensitivity of the tissue being exposed. For example, exposure to 1 Sv of gamma radiation is considered to increase the risk of cancer by approximately 5%, while exposure to 1 Sv of alpha radiation can cause severe damage to the skin and internal organs. In order to protect individuals from the harmful effects of radiation, regulatory agencies such as the International Commission on Radiological Protection (ICRP) have established guidelines for safe levels of radiation exposure. These guidelines take into account the type of radiation, the sensitivity of the tissue being exposed, and the duration of exposure.

Sv
Sv is a term used to denote a fast shutter speed when talking about photography. It is often used when taking pictures of fast moving objects, as the shutter speed is faster than the normal speed and can capture the moving object without blurring. This applies to both digital and analogue photography, as well as film and video. Notable works created using Sv shutter speeds include the work of street photographer Vivian Maier, who famously captured fast-moving scenes on the streets of Chicago, and the work of fashion photographer Mario Testino, who captured models in motion in his much-celebrated fashion editorials.
