Интересный документ. Подробный. Удивило то, что при проведении работ некорректно отработала автоматика.

The temperature of the assembly and the neutron and gamma fluxes are constantly monitored, and if preset levels are exceeded the system is automatically shutdown by the action of promptly lowering the lower part of the assembly to stop the chain reaction. Unfortunately, in the accident described in this report this automatic system did not actuate in sufficient time to prevent the overexposureof the technician, owing to the extremely short duration of the initial radiation pulse.

Плюс нарушение правил проведения работ:

Regulatory and technical documents of the Russian Federation Ministry for Atomic Energy specify precisely the procedural and management requirements for work with critical assemblies. They require that this type of work be conducted only by groups of trained technicians, with each person being responsible for strictly defined actions within a sequence of operations which are closely supervised.

В то время, как сотрудник работал один.

However, he was working alone in the experimental hall, which was a violation of documented procedure.

Плюс неосторожность/невнимательность/неаккуратность/неуклюжесть:

At 10:50, during the construction of the assembly, a component from the upper reflector slipped from the technician's rubber gloved hand and fell on to the lower part of the assembly, which had already been constructed and contained the enriched uranium core. (Gloves were routinely worn to prevent contamnation of the components of the assembly.) The point of criticality was exceeded, there was a flash of light and a wave of heat, and the lower part of the assembly was ejected downwards into the bottom of the stand.

Как изменялось состояние здоровья сотрудника описано тоже весьма подробно, вплоть до почасовых результатов анализов его крови приведено.

Изучаю дальше.

А что за вспышку он увидел "there was a flash of light and a wave of heat"? Кто-нибудь может объяснить?
