The blue powder was cesium-137, a highly radioactive material used in cancer treatment. When improperly handled, it became one of the most lethal substances on Earth, causing severe radiation poisoning.
A young man sold the cesium-137 capsule to Devayer Ferreira, who owned a scrapyard. The capsule was part of a disassembled radiation therapy machine from an abandoned cancer clinic.
Symptoms included vomiting, diarrhea, fever, severe stomach pain, radiation burns, and painful skin lesions. Many victims also suffered long-term medical conditions or amputations.
Maria realized that everyone who had fallen ill had come into contact with the blue powder. She took it to the public health agency to have it analyzed, suspecting it was the cause of the sickness.
Four people died, including Maria Ferreira and her niece Leiji. Many others suffered severe health consequences. The incident remains one of the deadliest disasters involving medical radiation.
Brazil's Nuclear Energy Commission was contacted, and thousands of residents were tested for radiation poisoning. The radioactive material was safely disposed of, and the abandoned clinic was demolished.
Doctors initially misdiagnosed her condition as a food allergy or tropical disease, failing to recognize the symptoms of radiation poisoning until it was too late.
Devayer Ferreira shared the blue powder with family, friends, and neighbors, who handled it directly or came into contact with contaminated items. The powder was also spread through physical contact and environmental contamination.
