Icru, the International Commission on Radiation Units & Measurements, has been providing essential guidance to the fields of radiation science, radiation medicine, and radiation protection for over 90 years. Their mission is to develop and promote internationally accepted recommendations on radiation-related quantities and units, measurement procedures, terminology, and reference data. They strive to ensure the safe and efficient application of ionizing radiation in medical diagnosis and therapy, radiation science and technology, and radiation protection for individuals and populations.

Established in 1928 during the Second International Congress of Radiology, Icru was initially focused on proposing a unit for measuring radiation in medicine. Over the years, its role expanded to encompass a wider field. The organization holds regular meetings and publishes reports on topics such as radiation science, radiation therapy, diagnostic radiology, nuclear medicine, and radiation protection.

Led by renowned experts and chaired by Vincent Grégoire of France, Icru continues to be at the forefront of research and development in the field of radiation. Through their comprehensive reports and recommendations, they contribute to the advancement of radiation-related practices worldwide
