Agreed.
Using current nominal probability coefficients for stochastic effects, would
that cancer risk enhancement for an average age person be from ~25% to ~47%
?
Anyone know the age of this "senior employee" and the corresponding
estimated risk numbers ?

Thanks

Brent:

 

An official communiqué (http://www.irsn.org/vf/docs/fleurus.pdf
<http://www.irsn.org/vf/docs/fleurus.pdf> ) leaves no room for doubting that
the employee received - more or less - a full body dose of 4.2 Gy
(uncertainty 3.8 to 4.5) within some 20 s. This source also describes the
casualty as an experienced senior employee who was specifically called from
home for helping the staff on site to turn off an alarm of unknown
causation. The senior employee in full compliance with the safety
regulations shortly inspected the irradiation room before locking up again
its door to make sure that no person stayed inside. This short mandatory
inspection led to his exposure.

What continues to amaze me is that at such high an exposure a particularly
experienced radiation worker took three weeks to realize that he suffered
from acute radiation thickness.

Presently he is receiving dedicated intensive professional care and
hopefully he will recover and hopefully his significantly enhanced cancer
risk does not materialize.
