An earthquake of 9.0 magnitude, followed by a tsunami, hit Japan in 2011 causing widespread destruction. Fukushima Nuclear Power Plant had been damaged, causing a spread of radioactive materials.

The aim of this study was to assess personal willingness to respond to a disaster as a part of an international delegation, to an area with unknown and unclear risk of radioactive materials. The Israeli delegation to the Japan 2011 earthquake had been chosen as a case study.

The survey was conducted during the first two weeks after the tsunami in Japan. The population was selected randomly. After distributing the survey form, 94 anonymous answers were received, which give a 69% participation rate. The sample was divided into two groups (participated or didn't participate in an international delegation in the past).

It was found that as the situation on the ground became worse, the willingness to be deployed dropped dramatically, although no significant difference was found in willingness between the two study groups. When both groups were combined into one group, significant differences were found in their willingness to be deployed in a delegation between the three levels (no radioactive leak, possible radioactive leak, and uncontrolled leak).

The willingness to serve on a delegation that responds to a scene with a potential radioactive leak will be dramatically influenced by the risk at the site.

Radioactive contamination can occur as a result of accidental or intentional release of radioactive materials (RM) into the environment. RM may deposit on clothing, skin, or hair. Decontamination of contaminated persons should be done as soon as possible to minimize the deleterious health effects of radiation. The goal of this study was to evaluate the decontamination efficiency (for residual contaminant) of the active components of “Shudhika,” an indigenously developed skin decontamination kit. The study kit is for external radioactive decontamination of intact skin.

Decontamination efficiency was evaluated on the skin surface of rabbit (n = 6) and human volunteers (n = 13). 99mTc sodium pertechnetate (200-250 μCi) was used as the radio-contaminant. Skin surface area (5 × 5 cm2) of thoracic abdominal region of the rabbit and the forearm and the palm of human volunteers were used for the study. Decontamination was performed by using cotton swabs soaked with chemical decontamination agents of the kit.

Decontamination efficiency (% of the contaminant removed) was calculated for each component of the study. Overall effectiveness of the kit was calculated to be 85% ± 5% in animal and 92% ± 3% in human skin surfaces. Running water and liquid soap with water was able to decontaminate volunteers' hand and animal skin up to 70% ± 5%. Chemical decontamination agents were applied only for trace residues (30% ± 5%). Efficiency of all the kit components was found up to be 20% ± 3% (animal) and 28% ± 2 (human), respectively. Residual contamination after final decontamination attempt for both the models was observed to be 12% ± 3% and 5% ± 2%. After 24 and 48 hours of the decontamination procedure, skin was found to be normal (no redness, erythema and edema were observed).

Decontaminants of the study kit were effective in removal of localized radioactive skin contamination when water is ineffective for further decontamination. By using the chemical decontaminants of the study kit, the use of water and radioactive waste generation could be reduced. Cross-contamination could also be avoided. During radiologic emergencies where water may be radioactively contaminated, the study kit could be used.

Training emergency personnel on the clinical management of a mass-casualty incident (MCI) with prior chemical, biological, radioactive, nuclear, or explosives (CBRNE)-exposed patients is a component of hospital preparedness procedures.

The objective of this research was to determine whether a Virtual Emergency Department (VED), designed after the Stanford University Medical Center's Emergency Department (ED) and populated with 10 virtual patient victims who suffered from a dirty bomb blast (radiological) and 10 who suffered from exposure to a nerve toxin (chemical), is an effective clinical environment for training ED physicians and nurses for such MCIs.

Ten physicians with an average of four years of post-training experience, and 12 nurses with an average of 9.5 years of post-graduate experience at Stanford University Medical Center and San Mateo County Medical Center participated in this IRB-approved study. All individuals were provided electronic information about the clinical features of patients exposed to a nerve toxin or radioactive blast before the study date and an orientation to the “game” interface, including an opportunity to practice using it immediately prior to the study. An exit questionnaire was conducted using a Likert Scale test instrument.

Among these 22 trainees, two-thirds of whom had prior Code Triage (multiple casualty incident) training, and one-half had prior CBRNE training, about two-thirds felt immersed in the virtual world much or all of the time. Prior to the training, only four trainees (18%) were confident about managing CBRNE MCIs. After the training, 19 (86%) felt either “confident” or “very confident”, with 13 (59%) attributing this change to practicing in the virtual ED. Twenty-one (95%) of the trainees reported that the scenarios were useful for improving healthcare team skills training, the primary objective for creating them. Eighteen trainees (82%) believed that the cases also were instructive in learning about clinical skills management of such incidents. Conclusions: These data suggest that training healthcare teams in online, virtual environments with dynamic virtual patients is an effective method of training for management of MCIs, particularly for uncommonly occurring incidents.

The response to incidents with chemical and radioactive substances has been shaped primarily by firefighters' experiences with hazardous material (HAZMAT) accidents. Globally, HAZMAT tactics consist of the main elements of: (1) appropriate use of personal protective equipment; and (2) cordons regulating access into and egress from designated zones. Detection and casualty decontamination are far less uniformly organized.

Review and analysis of open-source (medical-and first responder-oriented) English and German Ianguage literature; informal questionnaire survey of first responders in several European countries.

The initial on-scene measures during a HAZMAT response—cordoning off the scene and rescue out of the contaminated area—are done uniformly by fire service responders. In most cases, emergency decontamination of casualties at the scene (disrobing and flushing), is performed by firefighters, however, reliability appears variable. The probability of a coordinated patient handover from fire personnel to emergency medical services (EMS) staff is rated “low” by most sources.

In many countries, specialized casualty decontamination units have been commissioned and are operated by a variety of services: fire, EMS, military and civil protection.

Hospital decontamination facilities are in most countries still the exception and depend mosdy on local commitment. Substantial detection usually invalues only simple measurements performed by the first responders; specialized support is planned to be given mainly by military, civil protection and specialized laboratories.

Initial on-scene response to chemical/radiological incidents is fundamentally similar in most countries. However, distinctive differences beyond the first steps restrict the transferability of organizational solutions.
