Ionising Radiation, are we safe?
Posted on Oct 9, 2013 by Safe Radiation
Modern radiation safety protection principles are based on a no threshold linear relationship between the radiation dose and the detriment it can cause to exposed individuals. Although some scientists question the validity of this linear hypothesis, it is considered a safe approach in light of our current understanding about the harmful effects of ionising radiation.
Theoretically, the linear hypothesis means that even a tiny amount of radiation dose could be harmful although the probability of the harm will be infinitesimally small. In that respect perhaps there is no ‘Safe Radiation’, that is, other than our company.
Most developments and human activities have some risks and side effects associated with them.
Perhaps an analogy can be drawn between the road infrastructure in a city and the practices that use ionising radiation sources for industrial or medical applications. Roads are built with full knowledge that accidents can occur on them; so, a number of precautions are taken to ensure they are structurally safe. Signs are posted, traffic lights are placed, vehicles are registered and tested for road worthiness, drivers are trained and licences are issued. Speed limits are applied and policing also occurs. Similarly, ionising radiation sources are used when the benefit outweighs the risk. Regulatory limits apply and the dose is kept as low as reasonably achievable. The radiation emitting apparatus and the premises where such apparatus are kept are adequately designed and regularly assessed by accredited professionals. Monitoring devices are kept calibrated and certified. Also, the possession, relocation, disposal and use of radiation emitting devices should occur strictly according to standards and codes and there are penalties for non-compliance. And all this, despite the probability of radiation induced harm being much smaller than a road accident.
