Figure 4.

Medical decision-makers are responsible for treatment. An assessment of an individual's dose is made as in Figure 1. In the approach illustrated any person with a dose >2 Gy would be considered in need of immediate medical assessment and possible intervention. Those with doses above 4 Gy would require hospitalisation. For doses above ~0.75 Gy but below 2 Gy one would likely be considered for a dicentric chromosome analysis at some point to estimate additional lifetime risk of radiation-induced cancer. Those without medical conditions that need immediate attention would be sent from the acute medical management areas to ‘home’ so that those in immediate need of care can receive attention. Home may be their own home or some temporary shelter or other accommodation. People with minor injuries, even broken bones and some injury may be sent to non-acute medical care so that resources are used to address life-threatening injuries.
