Finally ending in , it provided a wealth of information on the long-term effect of radiation exposure. The Manhattan Project, the crash study undertaken during World War II to develop the first atomic bomb, led directly the second long term study of the effects of long-term radiation exposure, namely the study of the survivors of the bombs at Hiroshima and Nagasaki. Among the findings was that there does not appear to have been an increase of birth defects in those that survived the blasts. There have been, however, about cancer deaths that can be directly attributable to the bombings.
Throughout the Cold War, there was experimentation on both sides into the properties and uses of radioactive material in various test reactors and related sites, looking to harness both the strategically valuable offensive power of radioactive material for nuclear weapons and the potentially valuable uses in other fields such as medicine, radiography, and others.

Wild fires can spread at a rate of over 14 miles An accidental release of ionising radiation may also occur due to the incorrect storing, handling, transport or disposal of radioactive material or waste. There are a vast array of potential industrial incidents that response teams may need to manage. It may be a leak of ionising radiation due to damage to an x-ray generator used for security inspection or Positive Materials Identification PMI.
It may be the accidental release or loss of radioactive isotopes or sources in the process of non-destructive testing NDT. Radiation incidents can also occur as a result of road traffic accidents involving vehicles that transport radiological sources. As of , there had been more than serious nuclear accidents and incidents from the use of nuclear power. To date however there has been only one nuclear emergency in the US - the accident at the Three Mile Island Unit 2 TMI-2 nuclear power plant near Middletown, Pennsylvania, in - which remains to this day the most serious incident in U.
The Chernobyl incident in Ukraine, attributed to a combination of human error and violation of procedures has been well documented and underpins the need for thorough training and testing of all procedures and drills. In March , a tsunami that followed the Tohuku earthquake disabled the generators that would have powered the cooling system pumps at the Fukushima Daiichi nuclear power plant in Okuma resulting in catastrophic failure and subsequent release. While deliberate acts involving the use of a radiological source are thankfully rare, the potential impact on public safety is devastating and it is crucial that CBRNe response teams are comprehensively trained to handle such events.
Simulation also has a key role to play in the prevention of such activities. Improving radiation safety at nuclear power facilities remains a significant, ongoing concern for regulators, energy providers and the general public Industrial operatives, radiation safety officers, health physicists, military personnel and first responders rely on two essential pieces of equipment when dealing with live radiation incidents in order to monitor dose and dose rate:.
A typical device features an easily readable display and also provides an audible indication of the ionising radiation count or dose rate. The devices are often programmed to emit an alarm warning when a predetermined rate of radiation counts or dose has been exceeded. A dosimeter monitors the Hp 10 dose the depth dose of deep organs and the Hp 0.
An audible alarm or chirp rate increases with the rate of radiation intensity. Personal dosimeters can be worn to obtain a whole body dose and there are also specialist types that can be worn on the fingers or clipped to headgear, to measure the localised body irradiation for specific activities. While survey meters and personal dosimeters are both fairly straightforward items of instrumentation, the challenge for radiation safety instructors lies in providing trainees with opportunities to test their ability to use these devices in realistic training scenarios.
Radiation safety training has a crucial role to play in ensuring effective response to any radiological incident, whether it be large or small, accidental or deliberate A key objective of radiation safety training emergency preparedness is the ability for military personnel and first responders to be able to identify Electronic simulators are safe and environmentally friendly radiation training systems that can be used in a variety of scenarios both indoor and outdoor to teach:. Simulators can also offer significant time-saving advantages for training exercises as they remove the costly and time-consuming administrative effort normally associated with the transport, deployment and safe handling of radiological sources.
An electronic radiation simulator is a vital piece of CBRNe and Hazmat training equipment that ensures personnel are thoroughly prepared for real-life radiation incidents. In March , the UK Public Health Executive PHE , published the results of a survey that explored the radiological impact of the transport of radioactive material by The regulations establish a clear framework to Electronic radiation simulators provide trainees with first-hand experience of detectors that are identical to the ones they will use on a live incident. In doing so they can offer huge benefits for personnel responsible for radiation safety:.
The use of replica detectors ensures that trainees learn to trust the values displayed on their instruments, that they develop an understanding of the relationship between the measurements on their survey meter and their own personal dose readings and that they also experience and understand the real-time effects of Time, Distance and Shielding on their instrumentation and personal safety. Simulator detectors offer the opportunity for genuine immersion training. Replicating all the elements of a real-life incident exposes trainees to the range of emotional responses they may encounter in high-stress settings.
The use of simulators also means that training exercises can be repeated as many times as required without the need to decontaminate or to wait for radionuclides, used for teaching contamination monitoring, to decay prior to disposal. After action review AAR ensures trainees follow clearly set out procedures and that they understand when errors have been made, enabling mistakes to be rectified in future training exercises. The use of simulators offers a significant time-saving advantage for training exercises. They mitigate the costly and time-consuming administrative effort normally associated with the transport, deployment and safe handling of radionuclides to the training location.
Simulators also avoid the difficulty and expense in justifying the purchase of new or replacement sources for training, freeing the trainer to focus on the training and the trainees. Historically, CBRN training has been confined to specialist, controlled areas, usually on a military base and the training scenarios employed involved. The ability to be able to respond to any emergency CBRNe or HazMat situation, whether it be an accidental event or a deliberate act As with any form of simulation used in the context of training, some compromises have to be accepted.
The key is to strike the right balance between the desired training outcome and what is achievable. The dynamic ranges associated with radiation readings are also extremely large which can contribute to challenges in implementing simulation. Other techniques involving the temporary placement of a means to simulate the presence of radioactivity are more instructor friendly.
For contamination exercises, options include the placement of powder or liquid substances that can represent an actual contaminant, not just on people, but also on food. And being soluble, can be used to simulate contaminated water or for teaching coolant water sampling. These substances have the advantage of simulating cross contamination and are often ideal for teaching the handling of open sources in a laboratory environment.
Simulant contaminants can also represent radioactive material on mining or drilling equipment or used to teach soil sampling. Alternative methods enable the ability to hide a safe item underneath a surface such as clothing or a protective suit to simulate contamination. This method provides the instructor with the means to influence the maximum level or reading and to simulate partial or full decontamination based upon observation of the student's activity.
It also has the advantage that poor decontamination activity can be accurately represented. The ability to simulate contamination by virtual means is also possible by determining the physical position and orientation of the simulation probe in relation to a surface. To effect training in the correct use of an X-Ray probe for ground contamination monitoring, for example, a combination of GPS and distance measurement can be used. Simulation of Gamma and high energy Beta emitters present their own unique challenges but are, within reason, still feasible.
Simulation sources are able to represent either specific or mixes of radionuclides which can present simulated readings on simulated dose, dose-rate meters and spectrometers. The simulation of these effects is perhaps where compromise is relied upon to the greatest extent. The reality is that safe alternatives will not be subjected to the same degree of attenuation reduction in force as actual radiation.
Technology now means shielding can be represented to a sufficient degree to enable students to appreciate its importance for protection. However instructors need to clarify the differences, where appropriate, for the lesson being delivered. This may also vary depending upon the operational responsibilities of the trainee. Once again we rely upon the need to demonstrate an effect for the student to experience. For example, while a radio signal used to simulate Gamma will not penetrate a metal shield, there are means by which this can be effectively represented for training purposes.
There is also the need to consider the specific type of scenario you wish to simulate, whether it be:. Ultimately what is important is to clarify your training objectives to ensure the most suitable technology is applied to achieve the desired training results within the available budgetary constraints. The creation of realistic training scenarios is vital in ensuring that military crews and first response teams are prepared and equipped to handle actual detectors in real-life The Chemical Weapons Convention CWC , signed and ratified by state-parties globally, is a multilateral treaty that bans the use of chemical weapons under In this case study, firefighter Ross Smallcombe describes his experience of using using simulator radiation equipment in a radiation safety training exercise at the Ryde Fire Station on the Isle of Wight.
The fire station has an old abandoned holiday village down nearby which is used to train in many areas of rescue.
