The radioactive elements have various applications in different sector, however any and all activities related to such elements cause exposure and generate waste that can be hazardous to both environment and human population. Moreover, the human curiosity and dependency on these elements have led to multiple accidents that had an everlasting impact in the past and such incidents continue to happen in today’s world as well. Nuclear forensics, a term defined by International Atomic Energy Agency (IAEA) is an important part in country’s nuclear security. In order to understand the production, intended use, history of radioactive elements and to identify the forensic indicators in the illicit nuclear or radioactive materials, nuclear forensics utilizes various analytical methods of chemistry, physics, geochemistry etc. With an increase in the number of countries that are gaining access to nuclear energy for peaceful applications in power and medicine, risk of natural or artificial accidents involving radioactive elements is ever increasing. Therefore, development in micro analytical and post detonation techniques will serve a significant role in the future of nuclear forensics. Also, the formulation of policies in the fields of nuclear energy and regular check of their implementation holds an important place in various Energy Regulatory Boards and Safety Councils across the world.
