Understanding Ionising Radiation
Ionising radiation comes from radioactive materials and can damage human cells. There are three main types: alpha particles, beta particles, and gamma rays. Alpha particles are the largest but easiest to stop, while gamma rays are smallest but hardest to stop. Radioactive decay occurs as unstable atoms emit radiation and become more stable. Each type of decay changes the atom in a different way. Ionising radiation is dangerous as it can damage DNA in human cells and lead to cancer or genetic defects.

Indian ocean tsunami warning system warks.
The Indian Ocean tsunami warning system relies on two centers, the Pacific Tsunami Warning Center and a center in Japan, to analyze earthquake data and determine if a tsunami will occur and when it will arrive. If a tsunami is predicted, warnings are sent to countries in the Indian Ocean region through organizations like the Asian Disaster Preparedness Center to allow time for evacuation. This system was implemented after the deadly 2004 Indian Ocean tsunami to help detect future tsunamis and save lives through early warning.
Tsunami warning system
The document describes how the tsunami warning system in the Indian Ocean works. It consists of sensors to detect tsunamis, centers to analyze earthquake data (PTWC, JMA), and regional watch providers (RTWPs) that issue warnings. When an earthquake occurs, data is sent to analysis centers which determine the tsunami risk and send warnings to RTWPs. These regional groups then disseminate alerts to the public via email and news to help protect lives. The 2004 Indian Ocean tsunami that killed over 200,000 people showed the need for an improved warning system.
