Nuclear chemistry biological effects from

Radiation is a phenomenon characterized more by its ability to canse biological effects than where it originates. Radiation was hrst discovered by German scientist Antoine Henri Becquerel, who received the Nobel Prize of Physics in 1903 for his work. Many of the terms associated with radioactivity come from those early pioneers in radiation physics Wilhelm Conrad Roentgen (1845-1923) and Pierre (1859-1906) and Marie Curie (1867-1934), who also received the Nobel Prize in Physics in 1903 for their work on radiation. Ernest Rutherford (1871-1937) is considered the father of nuclear physics. He developed the language that describes the theoretical concepts of the atom and the phenomenon of radioactivity. Particles named and characterized by him include the alpha particle, beta particle, and proton. Rutherford won the Nobel Prize for Chemistry in 1909 for his work. 

Nuclear chemistry is the study of nuclear reactions, with an emphasis on their uses in chemistry and their effects on biological systems. Nuclear chemistr) affects our lives in many ways, particularly in energy and medical applications. In radiation therapy, for example, gamma rays from a radioactive substance such as cobalt-60 are directed to cancerous tumors to destroy them. Positron emission tomography (PET) is one example of a medical diagnostic tool that relies on decay of a radioactive element injected into the body.
