Semipalatinsk test site

Semipalatinsk test site The test site is located in Kazakhstan on the border of the Semipalatinsk (now East Kazakhstan), Pavlodar and Karaganda regions, 130 kilometers northwest of Semipalatinsk, on the left bank of the Irtysh River. The test site covers 18,000 km². On its territory there is the previously closed city of Kurchatov, renamed in honor of the Soviet physicist Igor Kurchatov, previously - Moscow 400, Bereg, Semipalatinsk-21, Terminus station. On geographical maps, this place is usually shown as “Terminal” (by the name of the station) or “Moldary” (a village that became part of Kurchatov).

The first nuclear weapons test in the Soviet Union took place on August 29, 1949. The bomb's yield was 22 kilotons. The creation of the test site was part of the atomic project and the choice was made, as it turned out later, very successfully - the terrain made it possible to carry out underground nuclear explosions both in adits and in wells. The first atomic bomb of the USSR - "RDS-1" The first atomic bomb of the USSR - "RDS-1" The first atomic bomb of the USSR - "RDS-1" The first atomic bomb RDS-1 The first atomic bomb of the USSR - "RDS-1"

The charge was tested on August 12, 1953 at the Semipalatinsk test site. Charge power up to 400 kilotons of TNT equivalent.

The world's most powerful experimental bomb is A602EN. The estimated capacity is more than 100 megatons of TNT equivalent. Tested at half power.

In 1961, the first underground explosion was carried out at the Semipalatinsk test site. A lake formed at the site of the ground explosion of the first atomic bomb. If you ever happen to get to Semey, at the bazaar you will definitely meet sellers with meter-long carp. Don’t rush to rejoice, local residents avoid them. Carp, similar to sharks, are found there in only one place - on Atomic Lake.

Professor Kharitonov picked up such a piece and took it as a souvenir immediately after the explosion. He subsequently died from radiation sickness. This piece, which is now called "Kharitonchik", is now kept in the museum of the Institute of Radiation Safety and Ecology, Kurchatov, Kazakhstan.

Slag into which the earth has been baked and still has background radiation.

Dosimetrists check the background radiation after the explosion.

Gene mutations among residents of Semipalatinsk are inherited. Mutations caused by radiation from nuclear tests at the Semipalatinsk test site are inherited. This is evidenced by the results of research by an international group of scientists from Great Britain, Finland and Kazakhstan. Representatives of three generations from 40 families were tested. Scientists compared the results of blood tests and genetic materials with data they received in Finland and Britain. Scientists have come to the conclusion that the radiation from the first nuclear tests reached through generations - to the grandchildren of those who survived these explosions. At the same time, the level of genetic mutations among residents in the Semipalatinsk region is one and a half to two times higher than among people in other regions of Kazakhstan. .

The Semipalatinsk nuclear test site was closed on August 29, 1991 by the decision of the government of the Republic of Kazakhstan, Decree No. 409 of the President of Kazakhstan. The popular anti-nuclear movement “Nevada - Semipalatinsk” and its leader Olzhas Suleimenov played a big role in this. In December 1993, according to the directive of the Minister of Defense of the Russian Federation, the Semipalatinsk test site, or officially the 2nd State Central Test Site, was disbanded. In the dangerous zones of the former test site, the radioactive background still reaches 10,000 - 20,000 microroentgens per hour. Despite this, people still live at the site. The territory of the landfill is not protected in any way and until 2006 it was not marked on the ground in any way. Only in 2005, under public pressure and on the recommendation of Parliament, work began on marking the boundaries of the landfill with concrete pillars and barbed wire. The population still uncontrollably and unauthorizedly uses the landfill for grazing livestock and collecting scrap metal. The Semipalatinsk nuclear test site is one of many nuclear test sites in the world where the population lives and uses it for agricultural purposes.

Slide 1

topic of work: “Semipalatinsk nuclear test site”

Completed by: 10th grade students Pashayan V. and Zevaev Sh.

Uvarovskaya secondary school I – III levels

Uvarovo, 2011

Slide 2

The Semipalatinsk Nuclear Test Site is the first and one of the largest nuclear test sites in the USSR, also known as “SNTS” - the Semipalatinsk Nuclear Test Site.

Slide 3

Location

The test site is located in Kazakhstan on the border of the Semipalatinsk (now East Kazakhstan), Pavlodar and Karaganda regions, 130 kilometers northwest of Semipalatinsk, on the left bank of the Irtysh River. The test site occupies 18,500 km².

Slide 4

The first nuclear weapons test in the Soviet Union took place on August 29, 1949. The bomb's yield was 22 kilotons. The creation of the test site was part of the atomic project and the choice was made, as it turned out later, very successfully - the terrain made it possible to carry out underground nuclear explosions both in adits and in wells.

Slide 5

On August 12, 1953, the RDS-6s thermonuclear charge with a yield of 400 kilotons was tested at the test site.

Slide 6

On November 22, 1955, the RDS-37 thermonuclear bomb was tested at an altitude of about 2 km by dropping it from an airplane.

Slide 7

After the entry into force of the International Treaty Banning Nuclear Tests in Three Environments (in air, space and under water), signed on October 10, 1963 in Moscow between the USSR, USA and Great Britain, only underground explosions began to be carried out at the test site.

Slide 8

Since 1945, more than 2,000 nuclear tests have been conducted around the world. Two-thirds of all Soviet tests - 468 nuclear explosions - were carried out at the Semipalatinsk nuclear test site (SIP), including 125 explosions on the surface of the earth and in the air. Hundreds of thousands of residents of Altai, Central and Eastern Kazakhstan in the 50s of the twentieth century regularly observed this magnificent and terrible spectacle - huge nuclear mushrooms in the sky.

Slide 10

As a result of many years of nuclear weapons testing, a huge amount of radioactive substances was released into the atmosphere.

Slide 11

The impact of nuclear testing on the environment and agriculture in the SIP region

The impacts of nuclear testing on the environment and agriculture are multifaceted and continue to change. The observed phenomenon can be called a “continuously threatening environmental problem” [with elements of an environmental disaster], the manifestations of which accumulate over decades, depleting local resources and, ultimately, exceeding the ability of the population to cope with them.

Slide 12

Excessive contamination with radioactive isotopes of cesium and strontium was discovered in the river. Chagan, Aschisu, Lake Balapan and other water bodies in the territory of the SIP. At least 4500 sq. km of SIP soil and hydrosphere are contaminated with these isotopes above established standards. The overall scale of environmental contamination (both within and outside the boundaries of the SIP) with plutonium is due to its use in tests in quantities of more than 290 kg. The contribution of its exposure to total public exposure and the associated risk is unknown.

Slide 13

Existing contamination with cesium, strontium, plutonium, and other fission products could result in significant public exposure if current and future land uses are not properly controlled. More than 10 million curies of radioactive substances are concentrated in underground cavities of nuclear explosions in the immediate vicinity (about 50 km) from the Irtysh River. There is a risk of these radionuclides migrating with groundwater towards the river. Recent isolated measurements showing elevated levels of tritium in boreholes adjacent to underground cavities confirm the existence of such movement.

Slide 14

Population health The incidence of children in these regions for 2002-2003 exceeded the republican indicators by 1.21-1.25 times and amounted to 107,584 per 100 thousand child population in the East Kazakhstan region and 120,479 in the Karaganda region - 90,235 and 103,846 in the Pavlodar region – 86602 and 103440 against the republican indicators for the indicated years of 78315 and 87619, respectively.

Slide 15

The oncological incidence of the population of the region is the highest in the republic and amounted to 1143 and 1121 per 100 thousand population in 2002-2003 in the East Kazakhstan region and 1121 in the Karaganda region - 688 and 635 in the Pavlodar region - 476 and 506 against the republican indicators for the indicated years 523 and 519 respectively.

Slide 16

The overall mortality rate in these regions remains high and amounted to 1229 and 1276 per 100 thousand population in 2002-2003 in the East Kazakhstan region and 1276 in the Karaganda region - 1237 and 1299 in the Pavlodar region - 1095 and 1152.

Slide 17

The region's water supply facilities do not meet sanitary requirements due to the lack of disinfection installations, the establishment of sanitary protection zones, and the untimely implementation of planned preventive work. At the same time, there is information about the release of radionuclides into groundwater in areas adjacent to the test site.

Slide 18

By decree of the President of the Republic of Kazakhstan N.A. Nazarbayev, the Semipalatinsk nuclear test site was officially closed on August 29, 1991. Today, the Republic of Kazakhstan is the first and so far the only country to voluntarily renounce nuclear weapons. However, heavily contaminated areas remained both on the territory of the landfill and in some nearby regions.

Since 1945, more than 2,000 nuclear tests have been conducted around the world. Two-thirds of all Soviet tests - 468 nuclear explosions - were carried out at the Semipalatinsk nuclear test site (SIP), including 125 explosions on the surface of the earth and in the air. Hundreds of thousands of residents of Altai, Central and Eastern Kazakhstan in the 50s of the twentieth century regularly observed this magnificent and terrible spectacle - huge nuclear mushrooms in the sky.

Slide 10

As a result of many years of nuclear weapons testing, a huge amount of radioactive substances was released into the atmosphere.

Slide 11

Impact of nuclear testing on the environment and agriculture in the SIP region The impact of nuclear testing on the environment and agriculture is multifaceted and continues to change. The observed phenomenon can be called a “continuously threatening environmental problem” [with elements of an environmental disaster], the manifestations of which accumulate over decades, depleting local resources and, ultimately, exceeding the ability of the population to cope with them.

Slide 12

Excessive contamination with radioactive isotopes of cesium and strontium was discovered in the river. Chagan, Aschisu, Lake Balapan and other water bodies in the territory of the SIP. At least 4500 sq. km of SIP soil and hydrosphere are contaminated with these isotopes above established standards. The overall scale of environmental contamination (both within and outside the boundaries of the SIP) with plutonium is due to its use in tests in quantities of more than 290 kg. The contribution of its exposure to total public exposure and the associated risk is unknown.

Slide 13

Existing contamination with cesium, strontium, plutonium, and other fission products could result in significant public exposure if current and future land uses are not properly controlled. More than 10 million curies of radioactive substances are concentrated in underground cavities of nuclear explosions in the immediate vicinity (about 50 km) from the Irtysh River. There is a risk of these radionuclides migrating with groundwater towards the river. Recent isolated measurements showing elevated levels of tritium in boreholes adjacent to underground cavities confirm the existence of such movement.

Population health The incidence of children in these regions for 2002-2003 exceeded the republican indicators by 1.21-1.25 times and amounted to 107,584 per 100 thousand child population in the East Kazakhstan region and 120,479 in the Karaganda region - 90,235 and 103,846 in the Pavlodar region – 86602 and 103440 against the republican indicators for the indicated years of 78315 and 87619, respectively.
