Here's another radiography event, with nonstochastic damage. I'm afraid
that it will take a fatality to get the regulators and users to take
radiography controls seriously.
The opinions expressed are strictly mine.
It's not about dose, it's about trust.

SUBJECT: Potential Radiography Overexposure
On September 25, 2001, a radiographer employed by Accurate Technologies
and working under their license with the State of Maryland, an Agreement
State, received a potential overexposure while working at McShane
Industries, located at 605 Pittman Road in Baltimore, MD. The
radiographer was using an Amersham 660B radiography exposure device
(camera) when a sealed source, containing 60 curies of Iridium 192,
became stuck in an extension connector which connected the guide tube to
an extension tube. The radiographer inadvertently thought that the
source was back in the shielded camera when he relocated the camera and
guide tube to set up his next shot. The radiographer did not use a
survey meter and he was not wearing a pocket dosimeter, whole body badge
or alarming rate meter. On September 29, the individual noticed a
burning and itching sensation of his fingers. On October 1, the
individual notified the Radiation Safety Officer (RSO) of Accurate
Technologies of the incident. The RSO sent the radiographer to a doctor
for medical treatment that same day.
The NRC contacted the physician who informed the Agency that, on October
1, the individual had erythema (reddening and swelling) on his fingers,
and currently has erythema on his palms as well. The results of blood
analysis were normal with the exception of the lymphocytes indicating a
number slightly less than the normal range. The NRC has put the
physician in contact with Radiation Emergency Assistance Center/Training
Site (REAC/TS) to ensure that the patient obtains proper medical
treatment.
The RSO conducted a re-enactment of the occurrence on October 3, 2001,
at the Baltimore temporary job site, and calculated the worker's dose to
his hands to be approximately 730 rem. The RSO also calculated the whole
body dose to be
approximately 40 rem with a worst case estimate of approximately 350
rem. The NRC occupational dose limit is five rem in one year.
An assistant radiographer on site during the incident apparently was not
exposed.
The States of Maryland, New Jersey and New York have been notified of
the event. This licensee has a license to perform radiography with the
NRC, the State of Maryland and the State of New York. The licensee and
the State of Maryland plan to conduct a re-enactment of the incident at
the Baltimore temporary job site on October 5, 2001. A Region I
inspector will observe the re-enactment.
The licensee has agreed to suspend operations in Maryland. The State of
Maryland also plans to conduct an inspection of the incident within the
next few weeks at the licensee's New Jersey facility. Region I will
provide support and plans to accompany State inspectors.
The Region I Public Affairs Office is prepared to handle information
requests.
This information is current as of 4:00 p.m., October 4, 2001.
