How the Inverse Square Law will help with 2013’s serious radiation leak

Written by Argon Electronics on 17 Sep 2013

If 2013 is an average year, then odds on there will be a serious radiation incident resulting in major injury or death. There have been over 200 in the last 50 years. Often, the first sign of the problem is when someone turns up at A&E.

Radiation is a hidden threat. You can’t see gamma rays. They could be part of a ‘dirty bomb’, an Improvised Nuclear Device or a hidden source of radiation. Eleven trainee border guards in Georgia from 1996-97 were exposed to twelve abandoned and hidden radiation sources with symptoms unrecognised by doctors for months.

Radiation and the Inverse Square Law

For any of us, apart from shielding, two key factors affect our exposure to radiation: duration, and distance.

Duration: If our exposure time is halved, then our radiation dose is halved.

Distance: This is where the Inverse Square Law kicks in. If we double the distance between us and the radiation source, we reduce the dose by a factor of 4. If we treble the distance, we reduce the dose by a factor of 9, and so on.

The mantra of ‘failing to prepare is preparing for failure’ has never been truer than here.

At Argon Electronics, we have been helping people all over the planet to prepare for radiation leaks with our training simulators. Working with the world’s leading detector manufacturers, we’ve produced the RDS -200-SIM, an extremely realistic gamma survey simulator that mimics the real Mirion RDS200 detector. This device is ideal for deployment in realistic training scenarios, where instructors can demonstrate the Inverse Square Law and the principles of shielding, and responders can learn how to protect themselves and the public.
