Atomic Energy

Nuclear and isotopic techniques can help us to better understand the world we live in. The data IAEA gathers with these techniques can lead to improved, science-based policy making, including in relation to climate change. We can study both land and water systems using various nuclear techniques to evaluate the effects of climate change on the environment. The IAEA uses nuclear science and technology to help countries monitor, mitigate and adapt to climate change. It gives guidance on how to preserve and restore the environment.

Scientific Forum

The obvious lesson from the pandemic is the lack of global preparedness. The IAEA dedicated its Scientific Forum to investigate how nuclear science can further help the world to prepare for future zoonotic outbreaks.

Particle accelerators have many applications in medicine, industry and research. These machines accelerate charged particles, such as electrons and protons, to high speeds, sometimes even close to the speed of light.

Scientists in Sri Lanka, through the IAEA’s technical cooperation programme, are now looking to a nuclear technique to enhancing tea plant productivity through increased genetic diversity.

Due to Imposed travel restrictions due to the pandemic, a new set of guidelines provide nuclear power plant operators an additional support tool until IAEA missions can resume. 

As the largest ecosystem on the planet, the world’s ocean is a pillar of climate regulation and a powerful source of solutions to the changing climate. IAEA scientists use nuclear and nuclear derived techniques to understand the processes and mechanisms that control the oceans and propose strategies to protect people and the marine environment from the impacts of climate change, pollution, habitat destruction and biodiversity loss.

IAEA reaches agreement with Iran to extend by one month the necessary verification and monitoring activities carried out by the Agency in the country ensuring continuity of knowledge.

meeting between IAEA and EBRD

The IAEA and the European Bank for Reconstruction and Development have agreed to continue to work together, and with Ukrainian authorities, towards safe and cost-effective solutions to decommission the Chornobyl Nuclear Power Plant and manage radioactive waste in the Exclusion Zone.

The UN marks the thirty-fifth anniversary of the accident at the Chernobyl nuclear power plant  (26 April 1986) – one of the most serious nuclear accidents in history. Hundreds of thousands of people were affected by radiation. Some 350,000 people were forced to leave their homes in severely contaminated areas, with a deeply traumatic and lasting impact on their lives. The Chernobyl disaster was contained by governments working with academics and civil society for the common good. It holds important lessons for today’s efforts to respond to the COVID-19 pandemic. Disaster knows no borders.

On March 2011, Japan’s Fukushima Daiichi nuclear power plant was hit by a powerful earthquake and huge tsunami. What progress has been made in nuclear safety since the accident?

Imaging from inside the body.

Find out how nuclear science plays a key role in the diagnosis and treatment of cancer, from medical imaging to radiotherapy to radiopharmaceuticals to sterilising medical equipment. Cancer is one of the main causes of death worldwide. 10 million people die each year from cancer and the number is growing. More than one third of cancer cases can be prevented. Another third can be cured if detected early and treated properly. The IAEA helps countries increase access to life-saving nuclear techniques.
