     Chernobyl Accident of 1986
The Chernobyl Plume: simulation of the path travelled across Europe by the radioactive cloud folowing the Chernobyl accident of 1986.
     Fukushima Daiichi Accident of 2011
Understanding the accident

Analysis by IRSN of the Fukushima Daiichi accident of March 2011

This film has been made to help viewers better understand the events that took place at Fukushima. In its current version, the film focuses entirely on the events that resulted in a core meltdown in three of the reactors at Fukushima. The management of the cooling systems for the fuel storage pools, and impact of the accident on plant employees, local population and the environment, are not covered.

The development of the accident 

This film presents the sequence of the accident at the Fukushima Daiichi plant in March 2011. It explains how the boiling water reactor (BWR) operated in Japan, describes the scenario of the accident and details the actions conducted during the crisis.
Produced 02/2012 - 13mn

Contamination of the environment

This film provides explanations on the consequences of the accident at Fukushima Daiichi on the environment. It addresses the radioactive releases and their consequences on the terrestrial environment in Japan and on the marine environment of the Pacific Ocean.

Health issues after the accident

This film provides explanations on the health issues related to the accident at the Fukushima Daiichi nuclear power plant. It addresses the emergency responses at the time of the accident, and the protection and long-term monitoring of populations.

Lessons learned from Fukushima

A new approach to nuclear safety

What will be the impact of the accident at Fukushima on nuclear safety in France and in the rest of the world? For Japan and for the nuclear industry, there will be a before and an after Fukushima.

Contamination of people and the environment

Six months after Fukushima’s disaster, most of the areas devastated by the earthquake and then by the tsunami on 11 March 2011, have been cleaned up.But on the site of the nuclear plant, the cores of the three damaged reactors must still be cooled by water injection, and radioactive particles that were released still pollute the surrounding lands. A contamination that needs to be reduced to minimize the doses in foods, limit health problems and save the economy of the region.

Living with radioactivity

From the 12th of March 2011, carried by the winds, the radioactive particles expelled from the damaged reactors reached the city of Fukushima, located sixty kilometers of the nuclear plant. Six months later, the ambient radioactivity reaches in some areas of the city more than 3 microSieverts per hour, about 25 millisievert per year. The 300,000 residents are not evacuated and must learn to live with the risk of contamination.

Crops and food protection

Six months after the nuclear disaster at Fukushima, up to eighty miles of the nuclear plant, we measure abnormally high radioactivity levels, especially in areas where it did rain or snow after March 15. Deposits of the particles released by the three damaged reactors have not only contaminated the land, but also the sea, where tons of highly contaminated water used to try to cool the reactor core were scattered.The future for Japan and its population is focused on food issues.

Response of the Japanese society

Since the accident at Fukushima, the population of contaminated territories organize themselves to deal with the consequences of radioactivity. The inhabitants of the region of Fukushima learn to measure contamination but also experiments, trying to discover, with the help of scientists, how they will, nevertheless, be able to continue to use their land and their livelihood.

     Radiation protection stories
X-rays: Man becomes transparent

X-rays: Man becomes transparent

On December 28, 1895, the German physicist Wilhelm Conrad Roentgen announced that he had just discovered something which he had baptized X-rays. With these rays, we can see the inside of objects, like bags and suitcases, but if you put your hand in front of them, it is the bones that appear!

The epic story of radium

Resuming the work by the French physicist Henri Becquerel, Pierre and Marie Curie gave the name "radioactivity" to the property possessed by certain elements of spontaneously emitting radiation. In 1898, Marie isolated polonium and radium, two elements thus for unknown and highly radioactive.
Produced 2007 - 11mn

The alchemists' crucible

In 1934, Irène Curie (daughter of Pierre and Marie Curie) and her husband Frederic Joliot discovered that it was possible to artificially produce radioactive atoms (or radioisotopes). This significant discovery led to another breakthrough discovery: the fission of uranium.

The first steps towards radiation protection

This film tells the story of the radiation protection from the discovery of X-rays and radioactivity at the end of the 19th century until today.

Nuclear fallout

Between 1945 and 1980, Russia, the United States, Britain, France and China carried out more than 500 atmospheric nuclear tests. Each explosion released large amounts of radioactivity into the environment. And then a test that went amiss – being three times more powerful than expected – made the world headlines.

Controlled areas

In a nuclear facility, areas exposed to radiation are most often located in what is called "controlled areas". Workers entering such area must wear special clothing and protective gear. Their profession, activities and work methods are inconceivable without some form of radiation protection.

Rays in the universe: radon

The earth contains a great many natural radioactive elements, such as uranium, thorium and potassium. Uranium, for example, is present in all rocks, and in particular granite rocks. When it decomposes, it gives rise to a radioactive family, ultimately forming lead, which is stable. Radon is one of the radioactive decay products of uranium. Its distinguishing sign is that it is a gas.

Rays in the universe: cosmic radiation

We live in a pool of radioactivity since the world began. An average of 240 particles per m² fall on France every second. This exposure caused by cosmic radiation accounts for 10% of the naturally originating exposure to which we are all subjected.

Radioecology: Monitoring Becquerels

As soon as the French nuclear industry took off in the early 1970s, it became necessary to monitor its facilities and control discharges with particular care.

Contaminated areas: The Sami after the Chernobyl accident

There are some parts of Europe where people still follow their ancestral way of life. In Lapland, in the far North, the Sami have been raising reindeer for centuries. They also fish, hunt and gather all the food this wild countryside dotted with lakes and forests can provide them. But since Chernobyl, much has changed...

The effects of radiation on our health

Ever wondered what our cells look like? Radiation (X-rays, radioactivity) is an aggressive source of danger capable of damaging our DNA molecules which carry our genetic heritage.

Healing rays

Radiography and nuclear medicine provide doctors with essential information needed to prescribe the appropriate treatment. But the risks of radiation must not be neglected.

International Conference Radon and Society: From Knowledge to Action

In April 2013, the Norwegian Radiation Protection Authority (NRPA) and IRSN organized an international conference, co-sponsored by WHO, on the prevention of radon risk in homes.

IRSN's standards and interlaboratory comparisons

IRSN's standards and interlaboratory comparisons

Delivering reliable results is the objective of laboratories in charge of radioactivity measurement in the environment. To make sure, these laboratories use “standards” (sample of radioactive material for reference) and participate in exercise to test their expertise and their methods.

Tritium measurement

Tritium measurement

Tritium is naturally present in the environment, and is also one of the main radionuclides discharged by nuclear activities. In what amounts is it found? How does it behave? IRSN's experts try to answer these questions every day, by measuring the presence of tritium in the environment..
