Radiation is considered one of the important scientific phenomena that has entered many fields of life, especially medicine, industry, and scientific research. Despite the concerns associated with it, radiation has great benefits when used correctly and safely. However, it may become a danger to human health and the environment when misused or when exposure occurs at high doses. In the medical field, radiation is widely used in the diagnosis and treatment of diseases. X-rays and computed tomography CT scans help detect injuries and diseases with high accuracy. Radiation therapy is also used to destroy cancer cells and reduce their spread inside the body, which has contributed to saving the lives of millions of patients around the world. Medical Physics is one of the most important specialties that works to ensure the safe and effective use of radiation inside hospitals. On the other hand, radiation can cause serious harm if it exceeds the permitted limits. Continuous exposure to radiation may lead to cell damage and increase the possibility of developing serious diseases, such as cancer and radiation burns. Nuclear accidents and radiation leaks are also considered among the most dangerous disasters that affect humans and the environment for long periods. Therefore, health and scientific institutions are keen to establish protective laws and procedures to reduce the risks of radiation, such as using protective clothing, reducing exposure time, and continuously monitoring radiation doses. In conclusion, radiation can be described as a double-edged sword. It has great benefits in serving humanity and developing medicine, but it can become dangerous when misused. Therefore, awareness and commitment to safety procedures are the foundation for benefiting from radiation and avoiding its risks. AL_mustaqbal University is the first university in Iraq.
