The Advisory Committee on X-Ray and Radium Protection was established in 1929. [1] Initially, the organization was an informal collective of scientists seeking to proffer accurate information and appropriate recommendations for radiation protection.
Its recommendations form the basis of radiological protection policy, regulations, guidelines and practice worldwide. The ICRP was effectively founded in 1928 at the second International Congress of Radiology in Stockholm, Sweden but was then called the International X-ray and Radium Protection Committee (IXRPC).

The linear no-threshold model (LNT) is a dose-response model used in radiation protection to estimate stochastic health effects such as radiation-induced cancer, genetic mutations and teratogenic effects on the human body due to exposure to ionizing radiation. The model assumes a linear relationship between dose and health effects, even for ...
In May 2018, the NCRP published the report of an interdisciplinary group of radiation experts who critically reviewed 29 high-quality epidemiologic studies of populations exposed to radiation in the low dose and low dose-rate range, mostly published within the last 10 years. [44] The group of experts concluded:
Radiation protection, also known as radiological protection, is defined by the International Atomic Energy Agency (IAEA) as "The protection of people from harmful effects of exposure to ionizing radiation, and the means for achieving this". [1]
These studies demonstrate that HZE radiation led to the progressive loss of neuronal progenitor cells in the SGZ at doses of 1 to 3 Gy in a dose-dependent manner. NCRP Report No. 153 [3] notes that “Mice were irradiated with 1 to 3 Gy of 12C or 56Fe-ions and 9 months later proliferating cells and immature neurons in the dentate SGZ were ...
The US-based National Council on Radiation Protection recommends the shield be installed by an expert and lead may be substituted for gypsum, steel or concrete providing suitable thickness. Additionally, visual contact should be considered whilst designing the shield to allow for constant monitoring of the patient.
Radiation emitted by radioisotopes or radiation generators is utilized in therapy for cancer or benign lesions and also in interventional procedures using fluoroscopy. There has been a tremendous increase in the use of ionizing radiation in medicine during recent decades and health professionals and patients are concerned about the harmful ...
