For Sam Harrison, magnet fishing was just an engaging hobby. Armed with a powerful magnet, he explored a murky industrial canal, hoping to turn up something unusual among old chains, scraps of metal, and discarded junk. Then, one day, his magnet latched onto an object that proved far heavier than his usual finds.

With great effort, Sam hauled a small metal container onto the bank. It was covered in a thick layer of rust and resembled an old safe or a sturdy steel box. He immediately wondered if something valuable might be hidden inside. After photographing the object, he contacted the police to report his discovery.

Once the container arrived at a secure facility, specialists set out to carefully open its outer shell. However, the work stopped abruptly. Just as one technician removed the first metal panel, a nearby police officer spotted a warning sign. The discovery instantly changed the situation: the officer recoiled and ordered everyone to drop their tools and evacuate the room immediately.

A large-scale operation soon unfolded around the facility. Sirens wailed in the streets, hazardous materials experts arrived, and nearby businesses were urgently cleared of people. The area was cordoned off to keep bystanders away from the potentially dangerous find.

Experts in protective gear examined the container using specialized equipment. The readings confirmed their worst fears: they detected elevated radiation levels near the metal cube.

Inside was a source of cobalt-60—a radioactive material used, among other things, in radiation therapy equipment. If handled improperly, such a substance poses a serious health risk. The object Sam mistook for a potential treasure turned out to be hazardous industrial waste that had been lying near a public path for an unknown period of time.

But how did this radioactive equipment end up in the canal? Investigators uncovered the answer by examining serial numbers and related documentation.

Investigators traced the events back to 2014. According to the investigation files, a medical center had contracted a third party to transport obsolete radiotherapy equipment to a specialized facility for safe disposal.

However, instead of fulfilling their obligations, the contractors allegedly sought to cut costs by avoiding the expensive process of handling hazardous waste. They dumped the radioactive unit into the canal and falsified paperwork to make it appear as though the equipment had been delivered to its intended destination. A forged receipt allowed them to close the matter and conceal the disappearance of the high-value, dangerous cargo.

Fortunately, medical evaluations of Sam and the police officers involved showed no signs of acute radiation sickness. Preliminary findings suggest that the protective casing limited radiation exposure during their brief contact with the container. Radiation safety specialists have since secured the hazardous source and placed it into safe, long-term storage.
