Low-cost system turns smartphones into emergency radiation detectors

Prompt, individual-based dose assessment is essential to protect people from the negative consequences of radiation exposure after large-scale nuclear or radiological incidents. However, traditional dosimetry methods often require expensive equipment or complex laboratory analysis.

    This costs “less than $70”.

    You can get a cheap Geiger counter for $50 today and it’s about the same size. I see some for $30-40. These are based on old, proven technology, not some new thing with new unknown problems and an app.

    Not that it isn’t neat, but it’s kind of a solved problem.

    To put this into perspective, a 10 Gray dose to the skin is high enough to cause permanent hair loss.

    A 10Gy exposure is well, well beyond hair loss range and into the fatal within days zone. The LD50 is 5Gy, LD99 is 9Gy IIRC. Methinks the author did not do their research on the topic.
