Radioactive practical joke

Just your typical nuclear horseplay at an Indian reactor:

Indian government officials say workers at a nuclear power plant in the country's south have been treated for poisoning after drinking water was deliberately spiked with radiation.

Routine tests showed 55 employees from the plant in Kaiga in the state of Karnataka had increased levels of the radioactive element tritium, which is used in nuclear reactors.

The Nuclear Power Corporation of India, which operates the country's civil nuclear facilities, said in a statement that preliminary enquiries revealed no radioactive leak or security breach.

"It is possibly an act of mischief," the statement said.

Here Sanjay, try some of this glowing water, it tastes like mint. Really.
