VIDEOS CRIIRAD

Comment mesurer la radioactivité ?
Une série de 11 modules vidéo réalisés par la CRIIRAD avec le soutien financier de la région Rhône-Alpes, au titre du programme 2009 de la convention pluriannuelle d’objectifs signée en 2007 entre le Conseil régional de Rhône-Alpes et la CRIIRAD.

 

Les 11 vidéos ci-dessous ont été tournées à la CRIIRAD en urgence le 16 avril 2011 pour permettre aux citoyens japonais de disposer d'un minimum d'informations techniques afin d'utiliser les appareils envoyés par la CRIIRAD. Il s'agit en particulier de compteurs Geiger grand public et de radiamètres professionnels envoyé à M Wataru Iwata.

CRIIRAD advice to citizens : how to use some radiation meters (videos prepared in April 2011 for japanese citizens)

- How to control the ambient level of radiation with portable devices? How to evaluate exposition to ionizing radiation? Is it possible to determine the level of contamination of soil and food samples?
- The purpose of this CRIIRAD video is to help Japanese NGO and citizens to evaluate the level of radioactivity of their environment and foodstuff.

Module 1
What is CRIIRAD ? What are the objectives of this video ?

Module 2
How to measure the natural ambient level of radiation?
Introduction to counts per second (c/s) and microSieverts per hour (µSv/h)

Module 3
What happens when radioactive releases of Fukushima Daiichi nuclear power plant
contaminate the atmosphere?

Module 4
How to control contaminated soil samples with a DG5 or a Radex ?
What is the most convenient device to control contaminated soils : DG5 or Radex ?

Module 5
Why is it important
- to do outdoor measurements at ground level and at 1 meter above ground ?
- to control the ambient level of radiation inside your home if you live in an area affected by radioactive fallout ?

Module 6
Can I control the foodstuff radioactivity with a DG5 or a Radex ?
Part 1 : is the DG5 (c/s) useful to determine the activity of iodine or cesium (Bq or Bq/kg)?
Part 2 : is the Radex (µSv/h) useful to determine the activity of iodine or cesium (Bq or Bq/kg)?

Module 7
Presentation of the Radex, a doserate monitor – µSv/h (version n° 1503)

Module 8
Presentation of the DG5, a gamma scintillometer – c/s

Module 9
Presentation of the LB123, a cumulated dose of gamma radiation and gamma doserate monitor – µSv and µSv/h

Module 10
Presentation of EPD (Electronet Personal Dosimeter)
which measure the beta and gamma dose to the skin and the whole body – µSv and µSv/h

Module 11
Pay attention to contamination risks : first to preserve your health, second to preserve the measurement devices
