The NukAlert keychain is a personal safety utility that can alert you to dangerous levels of radiation within your immediate area. If radiation levels are detected this personal dosimeter begins chirping loudly to alert you to danger. 

NukAlert Keychain Radiation Detector

This is especially handy for people whose jobs take them into dangerous situations that have the possibility of exposing them to radiation, such as soldiers, inspectors, and emergency response personnel. 

There has been a global spike in interest over personal radiation detectors ever since the nuclear reactor disaster in Japan raised concerns about ambient radiation levels and radiation cloud drifts that might affect people around and outside the direct area of the incident. 

Oftentimes, people looking for some solution for their personal protection are content to choose something as pared down as the NukAlert, which is not made to the same high quality standards required of professional and scientific grade radiation detectors. 

However, if you just want to guarantee yourself some peace of mind by ensuring you'll know if you enter an area that is swamped in radiation, you can rely on the NukAlert keychain to give you advance warning and allow you enough time to get to safety. 

The intensity of the alarm is calbrated to the intensity of the radiation in your immediate area. So, if you begin encountering small amount of radiation, the keychain will start to emit a steady clicking that will ramp up in intensity as radiation levels increase. 

The NukAlert is capable of producing a 61 decibel alarm, making it very loud and easy to hear even in most work sites that do not include heavy machinery. This makes it a solid choice for radiation monitoring equipment for first responders like police and medics. 

In addition to these key personal dosimeter features, the NukAlert is a pretty sturdy little device, and has been tested to remain operational following a six foot drop or submersion in liquid up to six feet deep.Keychain Rads Detector

While it's not intended for taking accurate scientific readings or professional-grade monitoring, the NukAlert keychain is ideal for people that want to ensure they're not being exposed to radiation, or at least to have some notification about a dangerous area so they can leave before radiation levels in their body can buid to dangerous levels. 

The NukAlert is currently retailing for $170 and has a dose chart on its back to show you what level of clicking and exposure correlates with what radiation dose. Although the NukAlert personal radiation detector won't save you against exposure, it will definitely give you advanced warning and prevent situations where you may have been exposed for a long period of time simply because you did not realize there were dangerous levels of ambient radiation around you.
