Radiobiology
Encyclopedia : R : RA : RAD : Radiobiology
Radiation biology is the interdisciplinary field of science that studies the biological effects of ionizing and non-ionizing radiation of the whole electromagnetic spectrum, including radioactivity (alpha, beta and gamma), x-rays, ultraviolet radiation, visible light, microwaves, radio wave, low-frequency radiation (such as used in alternate electric transmission, ultrasound thermal radiation (heat), and related modalities.
The interactions between electromagnetic fields (EMF) and organisms can be studied at several levels:
- radiation chemistry
- molecular and cell biology
- molecular genetics
- cell death and apoptosis
- dose modifying agents
- protection and repair mechanisms
- tissue responses to radiation
- high and low-level electromagnetic radiation hazards
- specific absorption rates of organisms
- radiation poisoning
- radiation oncology (radiation therapy in cancer)
