Biodosimetry is an essential tool for providing timely assessments of radiation exposure, particularly when physical dosimetry is unavailable or unreliable. For mass-casualty events involving public exposure to ionising radiation, it is paramount to rapidly provide this dose information for medical management of casualties. The dicentric chromosome assay is currently the most reliable accepted method for biodosimetry; however, in a mass-casualty scenario, the throughput of this assay will be challenged by its time-consuming nature and the specific expertise required. To address this limitation, many countries have established expertise in cytogenetic biodosimetry and started developing surge capabilities through setting up regional networks to deal with emergency situations. To capitalise on this growing expertise and organise it into an internationally coordinated laboratory network, the World Health Organization has created and launched a global biodosimetry network (BioDoseNet). In order to determine the existing capacity of BioDoseNet member laboratories, including their expertise and in vivo experience, involvement in national and international activities, problems, needs and prospects, an in-depth survey was conducted. These survey results provide significant information on the current state of emergency cytogenetic biodosimetry capabilities around the world.
