1The discovery of radium by Marie and Pierre Curie in 1898 marked a significant breakthrough in the field of radioactivity and nuclear physics.
2Due to its highly radioactive nature, handling radium requires specialized equipment and safety precautions to prevent exposure and contamination.
3Radium was once used in glow-in-the-dark watch faces, but its use has largely been phased out due to the health risks associated with radiation exposure.
4In medical applications, radium is used to treat certain types of cancer, such as prostate cancer, through a process known as brachytherapy.
5The extraction and processing of radium from uranium ores is a complex and highly regulated process due to the potential environmental and health risks involved.
