Radiation physics is the study of the emission, transmission, and interaction of ionizing and non-ionizing radiation with matter, focusing on understanding the fundamental principles and applications in fields such as medicine, energy, and environmental science. It plays a crucial role in developing technologies for medical imaging, cancer treatment, and nuclear power generation, as well as assessing radiation safety and protection measures.

Radiation Physics

Radiation physics

Ionizing radiation refers to energy emitted from atomic or subatomic particles that has enough power to remove tightly bound electrons from atoms, thus creating ions. It is used in various fields such as medicine, industry, and research, but poses health risks like cancer and radiation sickness if not properly managed.

ionizing radiation

Non-ionizing radiation refers to a type of electromagnetic radiation that does not carry enough energy to ionize atoms or molecules, meaning it cannot remove tightly bound electrons. It is generally considered less harmful than ionizing radiation and is commonly found in everyday technologies such as microwaves, radio waves, and ultraviolet light.

Medical imaging is a critical component of modern healthcare, enabling the visualization of the internal structures of the body for diagnosis, monitoring, and treatment of diseases. It encompasses a variety of techniques and technologies, each offering unique insights and applications, from X-rays and MRIs to ultrasounds and CT scans.

medical imaging

Cancer treatment involves a variety of strategies aimed at eradicating cancer cells, controlling their growth, or alleviating symptoms. These treatments can include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted therapy, among others, and are often used in combination to maximize effectiveness.

nuclear power generation

Radiation safety involves implementing measures to protect people and the environment from harmful effects of ionizing radiation, ensuring exposure is kept as low as reasonably achievable (ALARA). It encompasses understanding radiation sources, monitoring exposure levels, and applying protective strategies such as time, distance, and shielding.
