The chernobyl accident an epidemiological perspective essay

Conclusions Summary The accident at the Chernobyl nuclear reactor that occurred on 26 April was the most serious accident ever to occur in the nuclear power industry. According to the reports published by government in Ukraine, this nuclear accident had lost hundreds of dollars.

All the radiation fumes would be floating in the air, what are the affects. Furthermore, because of the long induction period for most cancers, it is too early to evaluate the full radiological impact of the accident. A statistically significant excess relative risk of 4. Introduction I. A contributing factor was the variation of meteorological conditions and wind regimes during the period of release. Studies of the Chernobyl accident exposure might shed light on the late effects of protracted exposure, but given the low doses received by the majority of exposed individuals, any increase in cancer incidence or mortality will be difficult to detect in epidemiological studies. This group consists of approximately , individuals, of whom about , worked at the reactor site and the surrounding 30 km zone in and , when doses were highest It is made up of 2. Around 7, tonnes of steel and , m3 of concrete were used to cover the reactor. In this case the unit 4 of the Chernobyl plant was in a corpse in hoped to be buried for good. Nagasaki Symposium on Chernobyl: Update and Future. The advantages of using nuclear power absolutely can be eco-friendly because to build nuclear power plants does not require a lot of space and it does not contribute carbon dioxide and smoke particles gases to pollute the atmosphere In a society that gets more violent as each decade passes, the undeniable fact that individuals of the homo sapiens society will be their own undoing have been be taking shape quite clearly.

Humans are exposed to radiation more than they realize. Within the territory of the former Soviet Union, short-term counter-measures were massive and, in general, reasonably timely and effective. In a recent IARC International Agency for Research on Cancer case-control study of thyroid cancer among female as well as male clean-up workers from Belarus, Russia and the Baltic countries, individual external and internal radiation doses were reconstructed for thyroid cancers and matched controls After several years of accumulation of dosimetric data from all available sources and dose reconstruction calculations based on environmental contamination data and mathematical models, it is now possible to arrive at a reasonable, although not highly accurate, assessment of the ranges of doses received by the various groups of population affected by the accident.

The present understanding of the late effects of protracted exposure to ionizing radiation is limited, since the dose-response assessments rely heavily on studies of exposure to high doses and animal experiments.

The lessons that could be learned from the Chernobyl accident were, therefore, numerous and encompassed all areas, including reactor safety and severe accident management, intervention criteria, emergency procedures, com-munication, medical treatment of irradiated persons, monitoring methods, radio-ecological processes, land and agricultural management, public information, etc.

Continued follow-up of the exposed population will be essential to an accurate description of the dynamics of the epidemic and prediction of future risk. Further careful follow-up of these populations, including the establishment and long-term support of life-span study cohorts, could provide additional important information for the quantification of radiation risks and the protection of persons exposed to low doses of radiation.

Lives have been seriously disrupted by the Chernobyl accident, but from the radiological point of view, generally positive prospects for the future health of most individuals should prevail.

A prospective cohort of 8, Chernobyl Ukrainian liquidators was set-up to review this issue. The doses to these people ranged from a few grays to well above 10 grays to the whole body from external irradiation and comparable or even higher internal doses, in particular to the thyroid, from incorporation of radionuclides.

It also published an account of the accident, and its global fallout and exposures: Exposures from the Chernobyl accident 74 pages. Not only was miles around the plants irradiated, citizens and workers were exposed to higher levels of radiation, the workers even being developing acute radiation sickness.
