Safecast is an international, volunteer-centered organization devoted to open citizen science for environmental monitoring.Safecast was established by Sean Bonner, Pieter Franken, and Joi Ito shortly after the Fukushima Daiichi nuclear disaster in Japan, following the TÅhoku earthquake on 11 March 2011 and manages a global open data network for ionizing radiation and air quality monitoring.
Radiation monitoring involves the measurement of radiation dose or radionuclide contamination for reasons related to the assessment or control of exposure to radiation or radioactive substances, and the interpretation of the results. [1] The U.S. Navy monitored radiation from the Fukushima I nuclear accidents
A reading is taken from each of the over 200 stations every hour [2] [3] and an alert triggered if radiation levels for specific isotopes rise significantly above normal background radiation levels at one or more stations. RREMS replaced the older Radioactive Incident Monitoring Network (RIMNET) system in September 2022. [4]
The World Radiation Monitoring Center (WRMC) is the central archive of all Baseline Surface Radiation Network measurements. In 1992 the WRMC was founded at ETH Zurich. Since 2008-07-01 the WRMC is hosted by the Alfred Wegener Institute. Data were transferred to AWI from the original ftp-site at ETH Zurich until about 2008-03-01. More recent ...
To monitor the background (least influenced by immediate human activities which are regionally concentrated) shortwave and longwave radiative components and their changes with the best methods currently available. To provide data for the calibration of satellite-based estimates of the surface radiative fluxes.
Radiation monitors in general have a number of process-control applications in nuclear power plants; [9] a major CPAM application in this area is the monitoring of the air intake for the plant control room. In the event of an accident, high levels of airborne radioactivity could be brought into the control room by its HVAC system; the CPAM ...
The main scientific purpose of FORUM is to better understand the Earth's radiation budget - the balance between the incoming radiation mostly from the Sun at short wavelengths, and outgoing radiation, which is a combination of reflected radiation from the Sun and radiation emitted by the Earth system, much of it a longer wavelengths - and the ...
One of four example estimates of the plutonium (Pu-239) plume from the 1957 fire at the Rocky Flats nuclear weapons plant. The Rocky Flats Plant, a former United States nuclear weapons production facility located about 15 miles (24 km) northwest of Denver, caused radioactive (primarily plutonium, americium, and uranium) contamination within and outside its boundaries.
