Topics like mobile phone radiation are always controversial, but if you're in the camp that believes there is a legitimate health risk associated with spending too much time on your BlackBerry you will be happy to know that the folks at Tawkon have released a free ad-supported version of their app.

If you didn't see our original blog post about Tawkon, you'll want to check that post out for some lively discussion and also the video above to get an overview and walk through of the app. In general, Tawkon is an app that operates on one basic premise - monitor the radiation emitted by your BlackBerry. Beyond that, Tawkon takes this one step further, not only notifying you of rising radiation and a predefined threshold, but also offering suggestions as to how to reduce the level, without interrupting your normal usage. It attempts to be as non-intrusive as possible, while maintaining the highest possible level of safety. Specific features include:

  • Predictive Mode allows you to preview your potential exposure prior to making a call, based on current conditions, such as your location on their "radiation zones" map. This is displayed to the user with easy to understand colour-coded signs, ie: green for minimal exposure to radiation.
  • Call Mode monitors your current conditions while in a call, providing intelligent solutions and feedback, such as engaging speaker-phone, or moving back to a previously "safer" location.
  • Statistics - The app also features a full set of statistical data tools, showing you how much radiation you have avoided by using the apps suggestions, accumulation of radiation, and radiation during the last call.

The premium ad-free version of Tawkon normally sells for $9.99, but at the time of this writing is currently on sale for $4.99. And of course the new ad-supported version is FREE, so whether you're a believer or skeptic there's no cost associated with giving it a download and try it out for yourself.
