Radiological Incidents and Dirty Bombs: Overview

Newrisk Limited is available to advise organisations and governments on radiological incidents and dirty bombs.

Newrisk Limited and its principal adviser, Dr Leivesley, have previous experience in advising organisations and governments on radiological incidents and the threat of contamination arising as a result of a dirty bomb. Dr Leivesley trained as a Scientific Adviser with the Home Office and undertook further studies in Advanced Radiobiology for this work.

Since 2011, Dr Leivesley has undertaken extensive research on the Fukushima Daiichi nuclear power plant accident (arising as a result of the earthquake and tsunami on 11 March 2011). Extensive research into the daily risks to the affected region and to Tokyo from the release of radiation from the nuclear power plant accident has provided a basis for analysis of the potential effects of radiation from dirty bombs on major cities with important international financial roles. Papers will be forthcoming (throughout 2012) on the Fukushima effect and the lessons for the protection of populations, halting secondary radiation contamination of the environment and critical infrastructure as well as recovery from future severe nuclear incidents that may arise from terrorist acts or international conflicts.

  • TEG7
  • Cyber Threats

In response to the Paris & Brussels terror attacks, Newrisk Ltd became a founder member of The Exercise Group7 LLP (TEG7) which is a dynamic team drawn from cyber & former special defence fields to exercise organisations & governments on emerging terror and cyber threats.  The TEG7 profile can be seen at www.teg7.co.uk. The Manchester Arena suicide bombing in May 2017 highlights a new military style of terrorism from ISIS with a greater potential to attack the public & security personnel in many countries.  TEG7 integrates physical & cyber security for corporate exercises to protect against terror & cyber-attacks.

Delta & British Airways have suffered a world-wide loss of aviation business systems as a result of computer system outages.  Newrisk Limited - as part of The Exercise Group7 LLP - conducts exercises in integrated cyber & physical security transformation for companies & governments.  Cyber threats are becoming more serious for critical infrastructure & require new principles in management & exercises of personnel to pre-empt crises. Degraded operations will become a fall-back if persistent attacks continue to exploit vulnerabilities & use ransomware or nation state motivated attacks. The Ukraine power grid attacks are a key lesson for infrastructure protection. Aviation remains the industry ‘canary’ for cyber failures.
