 The amount of nuclear material in the world is increasing steadily. It's very important that this material doesn't fall into the hands of terrorists. We know that criminal groups have tried to get hold of it. The International Atomic Energy Agency helps countries to keep nuclear material secure. We provide training to police and guards at ports, airports and borders to help them prevent smuggling. More than 10,000 people have been trained in the last six years alone. We have given countries over 3,000 devices for detecting nuclear and radioactive material. We have advised on nuclear security at major sporting events such as the Olympic Games and international soccer championships. We provide expert peer reviews of countries' nuclear security systems and advice on ways of improving them. We help countries to securely manage radioactive material when used in cancer treatment and when it's no longer needed. The IAEA greatly values the cooperation with our partners in industry who develop the technology that helps us to prevent nuclear terrorism. Responsibility for nuclear security rests with each individual country. However, the consequence of a major security failure could be a catastrophe that transcends borders. This means international cooperation is vital. Cooperation will be strengthened when an important legal instrument known as the amendment to the Convention on the Physical Protection of Nuclear Material finally enters into force hopefully this year. The amendment will reduce the likelihood of terrorists being able to detonate a radioactive dispersal device otherwise known as a dirty bomb. This could cause many deaths and injuries, contaminate a large urban area and lead to mass panic. The amendment will also reduce the risk of a terrorist attack on the nuclear power plant that could create a massive release of radioactivity. Much progress has been made in improving nuclear security throughout the world, but we can never relax our guard. The IAEA is the global platform for cooperation in nuclear security. We will continue to help strengthen nuclear security everywhere in the coming years.
