Overexposure to Nuclear Medicine Technologist

In February 2015, it was determined that a nuclear medicine technologist received a cumulative annual whole body dose of 110 mSv (11 rem) for the time period of September 01, 2014 to January 07, 2015, which exceeds the annual statutory dose limit of 50 mSv (5 rem). The State completed their investigation and confirmed the validity of the whole body dose on July 13, 2015. The staff member received 100 mSv (10 rem) for 2014 and 10.1 mSv (1.01 rem) for 2015.

Uncontrolled release of radioactive effluents into the public sewerage system

On 2nd August 2013, ASN was informed by the Haut-Lévêque hospital in Pessac that an abnormal level of radioactivity had been discovered in a wastewater drain pipe. Investigations showed that radioactive effluents from the vectorised internal radiotherapy rooms were being discharged directly into the public sewerage network instead of being routed to the radioactive decay tanks, between August 2012 and 27th July 2013, owing to a piping connection error. The connection had been defective since works were carried out in August 2012.

A practitioner’s regulatory annual exposure dose limit was exceeded

On 14th October 2014, ASN was informed by Bordeaux CHU that the regulatory annual whole-body dose limit of 20 mSv was exceeded by an orthopaedic surgeon while using an interventional radiology device (image intensifier) in the operating theatre.

The event came to light when the practitioner’s passive dose monitoring results were received and showed that the dose received between June 2013 and June 2014 was 25 mSv.

Overexposure to Member of the Public

The patient received 555 MBq (15 mCi) of I-131 for therapy conducted from March 22, 2013, through March 29, 2013. During the patient’s hospitalization, visitors, including family members, were provided with radiation badges to monitor exposure. The badges were processed by Landauer on May 5, 2013, and the results of the badge reading indicate that a family member appears to have received 59 mSv (5.9 rem) effective dose equivalent during the period of the patient’s hospitalization.

Interventional Radiology - Exceeding of the maximum regulatory annual effective dose

On 30th May 2013, ASN was informed that the passive dosimeter results for a radiation therapy technician in Saint-Eloi hospital of the Montpellier CHRU had integrated over the last quarter of 2012 an effective dose of 32 mSv. This result is higher than the regulation annual limit set at 20 millisieverts.

The hospital initially assumed malfunctioning or incorrect use of the dosimeter. Upon receipt of the incident notification, ASN then asked the hospital to investigate further and to report on the occupational physician’s conclusions.

Exposure of workers performing industrial radiography

In October 2013, four workers were exposed performing industrial radiography at a building construction site of a thermo power plant in Slovenia. The dosimetry service reported the received doses of 27.5 mSv, 19.18 mSv, 2.62 mSv and 1.86 mSv in one month period. The received doses of all four workers exceeded a monthly dose constraint of 1.6 mSv. The total received annual doses of two workers were 32.25 mSv and 20.52 mSv exceeding the statutory annual dose limit for occupationally exposed workers of 20 mSv.

Overxposure of an industrial radiographer

On 14 September 2013 an employee of a company for non-destructive material testing was exposed to high radiation in a refinery in Lower Saxony. The evaluation of the employee's official dosimeter showed a radiation exposure of about four times the statutory annual dose limit for occupationally exposed persons. The affected employee had a whole body exposure of 75 mSv (statutory annual dose limit for occupationally exposed workers is 20 mSv). In addition on the left hand considerable skin redness and burns have occurred.
