Chernobyl: Crhonic survivers are OK.

For 2 decades, the necessity and mother nature come forcing an organic astonishing biological experiment. In 1986, to little of having happened the explosion of the nuclear reactor No. 4 in Chernobyl/Ukrania that elevated the surrounding temperature to 2500 g. C, for ignition of graphite bars, sending radionucleides to the atmosphere (100 times more radiation than the bomb of Hiroshima: Yevgeny Velikhov), 336 000 people were evacuated of the alienation zone (30 km of diameter), where exploited the reactor. It was expected that in the following years, radioactive Iodine present in trees and animal milk and Sr-90/Cs-137, pollutants of the floor (periods of semidesintegratión: 30 years) would affect vegetables, animals and surviving humans. It was expected also that the radioactivity will affect the health (cancer and mutations), of local populations during several generations. Forum Greenpeace (2005), has estimated in 270,000 the cases of cancer induced in Chernobyl (of those :93,000 would have died). Not all accept these figures: Chernobyl Forum, alone accepts 4,000 thyroid cancer deaths, all in childrens. The interesting thing, is that months after having happened the disaster, many people (bigger than 50 years), began to return and to live in the alienation zone. Today after 21 years, many survivors exhibit relative good health, what has made wonder to some if it was correct to evacuate so much people, generating social disruption and even bad health. Of another side, it is not less certain than eatable mushrooms (with radiation up to 8 times above the permissible), raspberries, cows, chickens and many wild many animals -never seen before- in the alienation zone, shine pompous today in natural conditioned reservations. Have the organisms of survivors, suffered a process of adaptation to the chronic radiation?. We rehearse some hypotheses.
I) Obviating the cases of acute radiation (death in hours or days, for bombing with high dose of neutrons and rays gamma: thyroid cancer and destruction of bone marrow), it was expected that chronic cases will appear in the following 10 years. And as after 21 years, most survivors, shine relatively healthy, it could happen that the period of latency between the exhibition and the appearance of the illness, last decades, being but probable that the exposed (bigger than 50 years) ones, die for other illnesses. The other, the fantastic would be that their organisms had developed adaptative mechanisms: II) as long as died dermic cells are replaced very fast, the skin would be protected by millions of emergent cells, requiring to revile her, high radiation dose. III) in healthy people, the cells of the small intestine are also constantly renovated and replaced by other new and alone high doses of radiation can interrupt this process, generating cellular death. Residents in the alienation zone, ingest for years, foods with high radiation levels (easily demonstrable in their stomachs), without happens them anything, the same one that vanishes with running of the hours, being possible that the digestive tract had developed efficient systems eliminators of radiation. Some studies point out that after the ceasing of small intestine cellular operation, they resumes its activity after a short period of recovery. IV) they would exist: radioprotectors generated by our own organism (sulfhydryl compounds) and other artificial ones like green tea extracts, conditions of free highly reactive radicals (scavengers) that somehow demand that the dose of reviling radiation be 3 times but high that the one calculated. Some Ukrainians, adduce that vodka, absorbs and eliminates the radiation of the digestive system.

Chernobyl, los sobrevivientes crónicos exhiben buena salud.
Desde hace 2 décadas, la necesidad y madre natura vienen forzando un asombroso experimento biológico orgánico. En 1986, a poco de ocurrida la explosión del reactor nuclear No. 4 en Chernobyl/Ukrania, que elevó la temperatura circundante a 2500 g. C, por ignición de barras de grafito, enviando radionucleidos a la atmósfera (radiación:100 veces mayor que la bomba de Hiroshima : Yevgeny Velikhov), 336 000 personas fueron evacuadas del alienation zone (30 km de diámetro), donde explotó el reactor. Se esperaba que en los años siguientes, el Iodo radiactivo, presente en árboles y leche animal y el Sr-90/Cs-137, contaminantes del suelo (periodos de semidesintegración de 30 años), afectasen a vegetales, animales y humanos sobrevivientes. Se estimaba que la radioactividad afectase la salud (cancer y mutaciones), de las poblaciones locales durante varias generaciones. Forum Greenpeace (2005), ha estimado en 270,000 los casos de cancer inducidos en Chernobyl (de los que 93,000 habrian fallecido). No todos aceptan estas cifras : Chernobyl Forum, solo acepta 4,000 muertes de cancer de tiroides mayormente en niños. Lo interesante, es que meses después de ocurrido el desastre, muchas personas (mayores de 50 años), empezaron a retornar y vivir en el alienation zone. Hoy tras 21 años, muchos de los sobrevivientes y retornantes, exhiben relativa buena salud, lo que ha hecho preguntarse a algunos si fué correcto evacuar a tanta gente, generando disrupción social y hasta –paradójicamente- relativa mala salud. De otro lado, no es menos cierto que hongos comestibles (con radiación hasta 8 veces por encima de lo permisible), frambuesas, vacas, pollos y muchos animales salvajes -nunca vistos antes- en el alienation zone, luzcan hoy rozagantes en reservas naturales acondicionadas. ¿Han sufrido los organismos sobrevivientes, un rápido proceso de adaptación a la radiación cronica?. Ensayamos algunas hipótesis.
I) Obviando los casos de radiación aguda y subaguda (muerte en horas o dias, por bombardeo con altas dosis de neutrones y rayos gamma : cancer de tiroides y destrucción de la médula ósea), se esperaba que los casos crónicos apareciesen en los siguientes 10 años. Y como tras 21 años, la mayoria de sobrevivientes, lucen realtivamente sanos, podria suceder que el periodo de latencia entre la exposición y la aparicion de la enfermedad, tarde decadas, siendo mas probable que los expuestos (mayores de 50 años), mueran por otras enfermedades. Lo otro, lo fantástico seria que sus organismos hallan desarrollado mecanismos adaptativos : II) En tanto, tejido con alta tasa de recambio celular, la piel estaria protegida por millones de células emergentes, requiriendose para injuriarla, altas dosis de radiación. III) En personas sanas, las células del intestino delgado tambien son constantemente renovadas y reemplazadas por otras nuevas y solo dosis altas de radiación interrumpen el proceso, generando muerte celular. Residentes en el alienation zone, ingieren desde hace años, alimentos con altos niveles de radiación (fácilmente demostrables en sus estómagos), sin que les ocurra nada, el mismo que se disipa con el correr de las horas, siendo posible que el sistema digestivo halla desarrollado eficientes sistemas eliminadores de la radiación. Algunos estudios señalan que tras el cese del funcionamiento celular del intestino delgado, este reasume su actividad despues de un corto periodo de recuperación. IV) Existirian :radioprotectores generados por nuestro propio organismo (compuestos sulfidrilo) y otros artificiales como los extractos de te verde, condicionantes de radicales libres altamente reactivos (scavengers), que de algún modo exigen que la dosis de radiación injuriante sea 3 veces mas elevada que la calculada. Algunos ucranianos, aducen que el vodka, absorbe y elimina la radiación del sistema digestivo.
