Systems and methods monitoring progress of a medical procedure by radiation exposure are provided. Locations of radiation producing and scattering items of medical equipment are received at a controller. Locations of individuals assisting with the medical procedure are received at the controller by way of tracking devices worn by the individuals during the medical procedure. The controller receives indication of when the radiation producing item(s) are activated and develops a radiation scatter intensity field. An analytical subsystem determines an estimated exposure level for each individual based on their position within the radiation scatter intensity field at each instance the radiation producing device is activated, which are compared to a benchmark. Where the estimated exposure level exceeds the benchmark, an intervention subsystem provides an intervention.

Medical source of neutrons, nuclear reactor for a medical neutron source, and method of application of a medical neutron source

A coolant having a set temperature is fed into the nuclear reactor core of a medical neutron source, which is in a subcritical state. The nuclear reactor core is transitioned from the subcritical state to a critical state until the nominal power of the nuclear reactor is achieved. A neutron output channel is opened in order to conduct a neutron therapy session, and the operation of the reactor is maintained at nominal power while the neutron therapy session is conducted. At the end of the session, the neutron output channel is closed at the same time as the reactor core is transitioned to a subcritical state. The temperature of the coolant entering the core is maintained unchanged and equal to a set temperature, both when the core is transitioned to a critical state and during the operation of the nuclear reactor at nominal power.
