Ĭhristopher Busby reported that the Ukrainian Ministry of Health, despite its optimistic beginnings went on to warn its readers against consuming local milk, berries, or mushrooms, in a pamphlet stated: Determining the elevated risk or a total number of deaths from low doses is completely subjective, and while much higher values would be detectable, lower values are outside the statistically significant reach of empirical science and are expected to remain unknown. Since 1986, the total death toll of the disaster has lacked consensus as the medical journal “The Lancet” and other sources have noted, it remains contested. There is a great deal of controversy concerning the accuracy of the methods used to determine the biological damage of nuclear power plant accidents. Scientific, Environmental, Geopolitical, and Economic Aspects The present paper correlates the increasing PC to the environmental dispersion of radioactive cesium-137. While the exact cause of PC is not known, certain risk factors associated with the disease include tobacco smoking, obesity, and both types of diabetes mellitus. Moreover, the death rate may increase more than that of other cancers because PC, unlike many other cancers, is still incurable. Despite advancement in the knowledge of potential risk factors that cause PC and in newly available tools for early diagnosis, its incidence is estimated to increase and will include 355,317 new cases up to the year 2040 in the U.S. Worldwide incidence and mortality of PC correlate with increasing age and are slightly more common in men than in women. Based on GLOBOCAN 2018 estimates, PC has been ranked as the 11th most common cancer in the world counting 458,918 new cases and causing 432,242 deaths (4.5% of all deaths caused by cancer) in 2018. PC is the seventh leading cause of global cancer deaths in industrialized countries and the third most common cancer in the USA. Temporal trends of deaths caused by the most frequent cancers and their forecast in the world from 2010 to 2030. But there is still a persistent, and not entirely disinterested, the controversy between damage from high and low exposure to ionizing radiations. Some methods of radiocesium removal and PC prevention are also suggested. Autoradiographic studies in mice have shown that 137-Cs is concentrated in greater quantity in the pancreas, particularly in exocrine cells, where most malignant PCs originate. 137-Cs, with a half-life of about 30 years, is still present in the environment for about 300–600 years. Published data in medical literature at World, European and Italian levels are reviewed and compared. The worldwide death rate of PC is increasing, but the exact cause is still not known. The Author studied the correlation between the geographical map of mortality from pancreatic cancer (PC) and the map of nuclear plant accidents, atomic bomb testing, and radioactive fallout. Ingested radiocesium can also cause in humans several cases of pancreatitis with secondary diabetes (type 3c), which are both on the rise in the world. Pancreas and salivary glands secrete Cs in the intestine thus eliminating about 14% of ingested Cs with the feces, the remaining 86% is eliminated by the kidney with the urine. In humans, animals, and plants cesium ion (Cs+) behaves like potassium ion (K+) and it is localized mainly inside the cells. The major artificial radionuclide present in the environment is cesium-137 (137-Cs). Radionuclide contamination in terrestrial ecosystems has reached a dangerous level.
