Grand Central Station Is More Radioactive Than a Power Plant

Radiation is a part of the natural world, so things made with natural materials often contain radioactive elements. In the case of Grand Central Station in New York City, the natural material is granite. All natural rocks contain traces of radioactive elements, but granite contains more than others, and certain specimens of granite contain especially high concentrations. It's worth noting that if Grand Central Station were a nuclear power plant, it would be shut down for exceeding the maximum allowable annual dose of radiation for employees. Wait for your train for an hour there, and you might be exposed to about 0.06 millirem, at least six times more than an airport scanner. The truth is we're exposed to radiation constantly. Let's take a look at your kitchen. The bananas are radioactive from their potassium, the Brazil nuts have a thousand times more radium than any other food item, and your dried herbs and spices were irradiated to counter bacteria, germination and spoilage. Not only that, but here's thorium in your microwave and americium in your smoke detectors. So, the next time you want to visit New York and are hesitant about visiting Grand Central Station, don't be. It's no more dangerous than your smoke detector.
