Sievert
The sievert (symbol: Sv) is a derived unit in the International System of Units (SI) intended to represent the stochastic health risk of ionizing radiation, which is defined as the probability of causing radiation-induced cancer and genetic damage. The sievert is important in dosimetry and radiation protection. It is named after Rolf Maximilian Sievert, a Swedish medical physicist renowned for work on radiation dose measurement and research into the biological effects of radiation.The sievert unit is used for radiation dose quantities such as equivalent dose and effective dose, which represent the risk of external radiation from sources outside the body, and committed dose, which represents the risk of internal irradiation due to inhaled or ingested radioactive substances. According to the International Commission on Radiological Protection (ICRP), one sievert results in a 5.5% probability of eventually developing fatal cancer based on the disputed linear no-threshold model of ionizing radiation exposure.
To calculate the value of stochastic health risk in sieverts, the physical quantity absorbed dose is converted into equivalent dose and effective dose by applying factors for radiation type and biological context, published by the ICRP and the International Commission on Radiation Units and Measurements (ICRU). One sievert equals 100 rem, which is an older, CGS radiation unit.
Conventionally, deterministic health effects due to acute tissue damage that is certain to happen, produced by high dose rates of radiation, are compared to the physical quantity absorbed dose measured by the unit gray (Gy). Provided by Wikipedia

Time for a paradigm shift? Exploring competition regulation and its relationship with the rising global burden of industrial epidemics by Benjamin Wood, Sven Gallasch, Nicholas Shaxson, Katherine Sievert, Gary Sacks
Competition regulation plays a key role in determining firm size, market structure, and what firms can do with their market power. In this paper, we explore how competition regulation in many countries has largely tolerated rising industry concentration and market power in harmful consumer product i...

Engineering the moss Physcomitrium patens to produce proteins with paucimannosidic glycans by Jessica Jonner, Benjamin Fode, Jonas Koch, Sören Boller, Paulina Dabrowska-Schlepp, Andreas Schaaf, Christian Sievert
Published 2025-07-01The moss Physcomitrium patens is an advantageous host for the production of biopharmaceutical proteins, particularly due to the ease of glyco-engineering. However, the ability to produce proteins with paucimannosidic (MM) glycans in this species currently depends solely on the nature of the product....

Consistency assessment of milk fat and protein percentages across 3 daily milkings in Holstein and Jersey dairy herds by Xiao-Lin Wu, Malia J. Caputo, Asha M. Miles, Ransom L. Baldwin, VI, Steven Sievert, Jay Mattison, John B. Cole, Javier Burchard, João Dürr
Published 2025-07-01Dairy cattle milking test plans in the United States and globally have evolved substantially since the 1960s toward cost-effective sampling methods. Test-day recording frequencies vary, adapting to the specific management needs of different herds. Typically, a cow is milked twice or more daily; howe...
