Thematic Session 2: Emergency Preparedness
- Steven Bell (National Physical Laboratory)
Following a nuclear or radiological event, radiation protection authorities and other decision-makers need rapid and credible information about the affected areas based on reliable radiological data. However, the potentially large areas and risks to people in the vicinity pose difficult measurement challenges.
Therefore, European joint research project “Metrology for Mobile Detection of...
Following a nuclear or radiological event, fast and appropriate radiation protection measures, based on reliable radiological data, are of high priority for decision makers worldwide. The nuclear accidents in Chernobyl (1986) and Fukushima (2011) are major examples where such protection measures were crucial. During events where a large radioactive plume is released to the atmosphere, it is...
The detection of natural radio-nuclides is of interest in several applications, for example for monitoring in natural or man-affected environments or for the identification and tracing of illegal radioactive materials. We designed and tested a camera for gamma-ray imaging based on the coded mask technique, able to detect a gamma-ray radioactive source with mrad precision. A first prototype...
The radioactivity monitoring for foodstuffs has been reinforced since the Fukushima daiichi NPP accident. The sample preparation procedures involving machining shall be required to homogenize radioactivity and fill a sample in the same type of container that is employed for the calibration. The conventional method, however, can be only used radioactivity monitoring by sampling surveys, even if...
Following a radiological incident, there is a need to rapidly monitor a range of sample types for multiple radionuclides to assess the risks to the public and the environment. Such rapid measurements will also be beneficial for high throughput routine monitoring of samples in and around nuclear sites.
This study describes the recent developments and comparison of methods for measurement of...
Monitoring and inspection of radioactivity in foods resulting from the nuclear accident at Fukushima Daiichi NPS in 2011 have been reinforced by local governments based on an inspection plan in accordance with the guidelines decided by the Nuclear Emergency Response Headquarters. The guidelines have been reviewed as necessary to ensure rational and efficient inspections with considering trends...
Measurements of radioactivity in fresh food are generally carried out in case of post nuclear accidents. In this case, only simple machining technique such as cutting, grinding is required for the sample preparation. For example, radioactivity monitoring for food has been reinforced since the Fukushima daiichi NPP accident and still carried out with such a sample preparation procedure. In such...
