 This was the first time that a formal meeting of the Commission took place independently of the ICR.At this meeting, ICRP became formally affiliated with the World Health Organization (WHO) as a ‘participating non-governmental organisation’.In 1959, a formal relationship was established with the International Atomic Energy Agency (IAEA), and subsequently with UNSCEAR, the International Labour Office (ILO), the Food and Agriculture Organization (FAO), the International Organization for Standardization (ISO), and UNESCO.
