    • Chernobyl disaster Hari Kulangara Viswanathan K0197996 E-mail:hkulangara@gmail.com
    • Industrial safetyIndustrial health and safety are crucial in anyhazardous plants such as oil and gas plants andnuclear plants. They are used to protect human,plant, and environment in case the process goesbeyond the control margins. Employers,employees and self employed to haveresponsibilities for industrial health and safety.
    • Chernobyl disasterApril 26, 1986, 1.23 am: At the Chernobyl NuclearPower Plant in Prypiat, Ukraine a test on reactornumber four goes out of control, resulting in a nuclearmeltdown. The ensuing steam explosion and fire killedup to 50 people with estimates that there may be up to4,000 additional cancer deaths over time among theapproximately 600,000 most highly exposed people.Fallout could be detected as far away as Canada.

    • Abandoned city - Prypiat
    • International spread of radioactivity•Four hundred times more radioactivematerial was released than had been bythe atomic bombing of Hiroshima.•Contamination from the Chernobylaccident was scattered irregularly inSweden , Iceland and Western Europe.
    • Chernobyl radiation map 1996
    • Chernobyl todayChernobyl unit 4 is now enclosed in a largeconcrete shelter which was erected quickly toallow continuing operation of the other reactorsat the plant. However, the structure is neitherstrong nor durable. The international ShelterImplementation Plan in the 1990s involved raisingmoney for remedial work including removal of thefuel-containing materials
    • What has been learnt from the Chernobyl disaster?The main ones concern reactor safety, notably in easternEurope. The International Atomic Energy Agency (IAEA)safety review projects for each particular type of Sovietreactor are noteworthy, bringing together operators andWestern engineers to focus on safety improvements.These initiatives are backed by funding arrangements.The Nuclear Safety Assistance Coordination Centredatabase lists Western aid totalling almost US$1 billionfor more than 700 safety-related projects in formerEastern Bloc countries.
