Eventually in 1987, two people came across the radiation source and took it with them.

The two attempted to open the casing, but were unable to. However, they did manage to break the iridium window, which allowed them to see the cesium rod emitting a deep Blue (from Old High German blao shining) is one of the three primary additive colors; blue light has the shortest wavelength (about 470 nm) of the three primary colors.

The sale to the junkyard owner led to many more people becoming contaminated:

• Junkyard workers hammered open the lead casing.

The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period. Many of the symptoms of radiation poisoning occur... radiation poisoning.
• A brother of the junk dealer scraped dust off the rod, spreading some of it on the floor of his house. His six-year-old daughter, Leide dos Neves Ferreira, later ate on this floor, absorbing some of the radioactive material. She died a month later, and was buried in a lead coffin.

She took it to a hospital, and the The word physician should not be confused with physicist, which means a scientist in the area of physics. A physician is a person who practices medicine. In the United States the term physician is traditional and commonly used.

A sensitive photomultiplier tube measures the light from the crystal. The photomultiplier (PMT) is attached to... scintillation counters.

She died a month later from the effects of the radiation, though she may have saved the lives of many others by finally disposing of the dangerous but innocent looking object.

Afterwards, about 100,000 people were examined for The radiation warning symbol (trifolium). Radioactive contamination is the uncontrolled distribution of radioactive material in a given environment.

It is unclear how many were exposed to the radiation itself. Of those contaminated, 10 people needed intensive care for Radiation poisoning, also called radiation sickness, is a form of damage to organic tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period. Many of the symptoms of radiation poisoning occur... radiation poisoning. It seems reasonable to assume that considerably more people died than are clearly accounted for.

In summary, the main cause of this incident was clearly the severe negligence of the former hospital management who left behind and forgot about such a dangerous item. The accident clearly demonstrated the importance of keeping an inventory and monitoring of all strong radiation sources by public authorities.
