radiation chemistry Introduction
Radiation chemistry, or radiochemistry, originated in the late 19th and early 20th centuries. Becquerel discovered in 1896 that the radiation emitted by uranium compounds can blacken negatives. Later, Pierre Curie and Madame Curie further developed radiation chemistry research in the related research of radium. Radiation chemistry is the study of ordinary chemical changes. The unstable isotopes of all elements undergo radioactive decay and the production of radioactive materials (called radioisotopes).
