The ICRU was conceived in 1925 to propose a unit for measuring radiation in medicine. It is now responsible for defining units of measure for radiation quantities and developing recommendations on their safe application. The ICRU works with committees to publish reports on topics like radiation therapy, dosimetry, and protection. Its goals are to evaluate data on ionizing radiation and maintain contacts to benefit radiation science.

- 1. ICRU CONCEPT DR KANHU CHARAN PATRO
- 2. History 1. The ICRU (originally known as the International X-Ray Unit Committee and later as the International Committee for Radiological Units) was conceived at the First International Congress of Radiology (ICR) in London in 1925 and officially came into being at ICR-2 in Stockholm in 1928. 2. The primary objective was to propose a unit for measurement of radiation as applied in medicine. From 1950 the ICRU expanded its role significantly to embrace a wider field. 3. Initially meetings were held every 3 years at ICR congresses (excluding the 13-year period encompassing World War II) with one physicist and one radiologist from each participating country having the right of attendance with the Chairman being nominated by the ICR host country. 4. A permanent Commission was elected in 1953

- 4. Administration The Commission's secretariat is in Stockholm and its legal status is that of British charity (Not-for-profit organisation).
- 5. Radiation quantities The commission has been responsible for defining and introducing many of the following units of measure. The number of different units for various quantities is indicative of changes of thinking in world metrology, especially the movement from CGS to SI units
- 6. SISTER 1. The ICRU is a sister organisation to the International Commission on Radiological Protection (ICRP). 2. In general terms the ICRU defines the units, and the ICRP recommends how they are used for radiation protection
- 7. AIMS 1. To collect and evaluate the most relevant data and information pertinent to the problems of ionizing radiation for inclusion in its reports. 2. To strive to maintain close contacts with organizations, professional societies and statutory bodies that benefit from its work.
- 8. MISSION To develop and promulgate internationally accepted recommendations on radiation related quantities and units, terminology, measurement procedures, and reference data for the safe and efficient application of ionizing radiation to medical diagnosis and therapy, radiation science and technology, and radiation protection of individuals and populations.
