Nuclearoha 

To poison a person or group of people with cement and construction material laden food or drugs to make them die slowly looking like radiation sickness or nuclear poisoning.
There was a man who went by Gary Kay but who’s real name was Gary Klemenz of Niagara Falls Ontario , who poisoned his ex and her son along with her granddaughter and granddaughter’s fiancé because he believed his son slept with his other son's mother and fathered his own brother . He used the cement , drywall compound , insulation and other materials in food to poison the ex so she died slowly over two years. At the same time he had poisoned his son with the same materials but added dog feces and other hazardous products to cause mycotoxins to grow and kill the son slowly over the course of time so it would look like natural death although the son deteriorated and was able to let the authorities know , but unfortunately not before he died a horrible death resembling nuclear poisoning, thus called nuclearoha.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
