Analytical methodologies for identification and quantification of radionuclides in food

Abstract

A radionuclide is an unstable form of an element that releases radiation as it decays. Studies have been conducted to determine the consequences of chronic and acute exposure to this type of radioactive substance. The objective of this article is to discuss the different analytical methodologies for the identification and quantification of radionuclides in food. The main naturally occurring radionuclides are presented and aspects related to the impact of these radionuclides on public health are addressed. The most important analytical methodologies for their determination in food are listed, as well as the advantages and disadvantages of each analytical method. Finally, the relevant findings obtained regarding radionuclide analysis are described, considering the used methodology and the food group studied.
