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
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.
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.
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]
Note that the monitor flowrate F m is assumed constant; if it isn't, and its time-dependence is known, then that F m (t) would need to be placed inside the integral. Also note that the time variable in all the models is measured from the instant the concentration in the sampled air begins to increase.
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 ...
Usually, the alarm of most RF personal monitors is triggered by instant values, however, standard limits are specified as time-averaged values. Some RF monitors have the possibility to trigger alarms based on average values, which is a better indication of the real exposure situation (as an example, an instant value can be at 200% while the ...
