Cobalt 60 contamination in Stainless Steel

A very similar event took place exactly here where I live, few miles from my home. A junk yard named Yonke Fenix allegedly received for recylcing a decomissioned X-Ray or a cancer treatment equipment from a local hospital

The unit was melted along with other scrap products, and several products were made with the iron which was contaminated with Cobalt 60

Then the products were sold into the USA and Mexico, until the contamination was discovered.

There is an article on this issue on the follonwing link:

No when I teach ISO 14971 (Risk Management) I explain what life cycle means using this example and how the risk associated with Medical Devices does not finish until the dvice has been properly decommisioned

There is nothing like a bad example to get a message across, and this one is applicable not only for medical devices. :agree1:

I work for North American Hoganas, a producer of iron powder in Pennslyvania, USA. All incoming scrap and raw materials used for steel making are screened for radiation. The main screening unit is calibrated regularly, and we have back-up calibrated hand units if it were to fail, or for use during calibration.

I'm not certain of the level it's set for, but it's fairly low as we can get false positives from residue of natural raw materials which were in a truck prior to delivering scrap - I believe gravel is one of the materials which requires that a truck be washed out prior to being used to deliver steel scrap.

thank you Claes Gefvenberg

it is really helpful to know how companies are approaching this issue and in fact that they are testing the steel and not just the scrap to make the steel
