The document summarizes the atomic bombings of Hiroshima and Nagasaki. On August 6th, 1945, the U.S. dropped an atomic bomb called Little Boy on Hiroshima, killing 70,000 initially and 130,000 from radiation over 5 years. On August 9th, another bomb called Fat Man was dropped on Nagasaki due to poor weather, killing 40,000 immediately and 60,000 injured. While more powerful, Fat Man caused less damage due to Nagasaki's terrain. These bombings ended World War 2 but began the nuclear era.
The document summarizes the bombings of Hiroshima and Nagasaki by the United States in August 1945. It notes that Hiroshima was bombed on August 6th by the Enola Gay dropping the atomic bomb Little Boy, killing 60,000-70,000 people. Nagasaki was bombed two days later on August 9th by Fat Man, resulting in 42,000 deaths and 40,000 injuries from burns and flying debris.
The document summarizes the events leading up to and outcomes of the atomic bombings of Hiroshima and Nagasaki at the end of World War II in the Pacific theater. It describes the estimated high costs of invading mainland Japan, the top secret Manhattan Project to develop nuclear weapons, and President Truman's difficult decision to drop atomic bombs on Japanese cities in light of Japan's refusal to surrender after the Allies demanded unconditional terms. On August 6, 1945, the U.S. dropped an atomic bomb called "Little Boy" on Hiroshima, killing 75,000 people instantly. Japan still did not surrender, so the U.S. dropped a second bomb called "Fat Man" on Nagasaki on August 9

The document summarizes the experiences of a 13-year-old boy who survived the atomic bombing of Hiroshima on August 6, 1945. He describes seeing the flash of light and feeling the shockwave from the bomb. His body was injured by glass and his clothing was covered in blood and shards. Survivors experienced radiation sickness in the following days from the radioactive fallout, suffering from fever, vomiting and hair loss, though at the time they did not understand the cause. The bombing killed over 200 schoolgirls who were mobilized to help in the city that day and could not receive care in time.
The document discusses the history and workings of atomic bombs. It notes that atomic bombs work through nuclear fission, which was discovered and developed into weapons during World War II under the Manhattan Project led by American physicist J. Robert Oppenheimer. The first atomic bomb was tested at Alamogordo, New Mexico in 1945. Two atomic bombs were then used against Japan in 1945 - "Little Boy" dropped on Hiroshima and "Fat Man" dropped on Nagasaki, causing widespread destruction and loss of life. The document outlines the effects of atomic bombs and some basic properties of the two bombs used against Japan.

The document discusses the 69th anniversary of the atomic bombings of Hiroshima and Nagasaki. It notes that around 140,000 people died in Hiroshima and 70,000 in Nagasaki either immediately or from radiation exposure by December 1945. The bombings precipitated Japan's surrender and the end of World War II on August 15, 1945. The atomic bombings were ordered by President Harry Truman and involved the nuclear attacks on the cities of Hiroshima on August 6, 1945 and Nagasaki on August 9, 1945, which put an end to World War II. It is estimated the bombs killed around 140,000 in Hiroshima and 80,000 in Nagasaki by the end of 1945

On August 6th, 1945, the United States dropped an atomic bomb called "Little Boy" on the Japanese city of Hiroshima, killing tens of thousands instantly. Three days later, on August 9th, the US dropped a second atomic bomb called "Fat Man" on Nagasaki, killing thousands more. The bombings marked the first use of nuclear weapons in war and resulted in hundreds of thousands of immediate and long-term casualties in Hiroshima and Nagasaki. Japan surrendered six days later, ending World War II.
1) In 1932, Einstein warned President Roosevelt about Nazi Germany's efforts to purify uranium, which could be used to create an atomic bomb. This led the US to begin the secret Manhattan Project to develop a bomb.
2) The Manhattan Project took 6 years and over $2 billion, led by Robert Oppenheimer. They successfully tested the first atomic bomb called "The Gadget" in New Mexico in 1945.
3) In early August 1945, the US dropped atomic bombs called "Little Boy" on Hiroshima on August 6th and "Fat Man" on Nagasaki on August 9th, causing widespread destruction and many casualties in both cities. Japan surrendered on August 15th, ending World
The document discusses the atomic bombings of Hiroshima and Nagasaki. It provides the rationale for the bombings, which was to end WWII and prevent mass casualties from a planned invasion of Japan. However, some people criticized the bombings on ethical grounds as civilians were targeted. After the bombings, over 220,000 people died from the two bombs. Japan surrendered six days later, ending the war.
The document summarizes the War in the Pacific between 1941-1945. It describes the key players, Japan's imperial expansion leading up to attacking Pearl Harbor in 1941. The US strategy involved "island hopping" to retake islands from Japan and cut off their navy. A turning point was the Battle of Midway in 1942 where the US sank four Japanese aircraft carriers. Fighting was brutal as the US advanced across the Pacific, culminating in atomic bombs being dropped on Hiroshima and Nagasaki in 1945. Japan formally surrendered on September 2nd, 1945, ending the most destructive conflict in human history.
The document summarizes the bombing of Hiroshima and Nagasaki in 1945. The US issued the Potsdam Declaration calling for Japan's surrender, but Japan refused. The US then decided to use atomic bombs, developed through the secret Manhattan Project, to force Japan's surrender and end WWII. On August 6th, the US dropped a uranium bomb on Hiroshima, killing 70,000 people. After Japan did not surrender, on August 9th the US dropped a plutonium bomb on Nagasaki, killing 135,000 people. Japan surrendered on August 14th, ending WWII.
The Manhattan Project began in 1939 and ultimately involved over 600,000 people including famous scientists like Einstein, Fermi, and Oppenheimer to develop the first atomic bombs. The Trinity Test in New Mexico in July 1945 was a success. At the Potsdam Conference, Truman was informed of this and warned Japan to surrender, but they did not. He ultimately decided to use the newly developed atomic bombs to end the war, dropping Little Boy on Hiroshima on August 6, 1945 and Fat Man on Nagasaki on August 9, 1945, together killing over 200,000 people. Japan surrendered on August 14, 1945, ending World War II.

The document summarizes the atomic bombings of Hiroshima and Nagasaki in August 1945. It describes the immediate and ongoing effects of the bombings, including the high death toll initially from burns and trauma (over 80,000 in Hiroshima and 40,000 in Nagasaki) and later illnesses from radiation exposure like leukemia. It also discusses the destruction of infrastructure in the cities and suppression of information about the bombings' impacts by the occupying Allied forces. The bombings marked the first and only use of nuclear weapons in war.

Hazarde Industriale
1. Hazarde industriale
Aceast categorie include o gam larg de accidente, declanate de om
cu sau fr voia sa, legate de activit釘ile industriale, cum sunt exploziile,
scurgerile de substan釘e toxice, etc.
Asemenea hazarde sunt frecvente 樽n industriile chimic i metalurgic,
dar si in industria nucleara datorit emisiilor de substan釘e nocive 樽n procesul
de produc釘ie i cantit釘ilor mari de deeuri care afecteaz solul, apa i aerul.
Amplasarea obiectivelor industriale 樽n vi ad但nci i depresiuni, 樽n care
se manifest frecvent fenomene meteorologice cum sunt calmul atmosferic
i inversiunea termic, conduce la stagnarea i cumularea poluan釘ilor i, 樽n
final, la realizarea unor concentra釘ii periculoase. Printre cazurile cele mai
semnificative se numr cele din vile Meusa, Belgia (樽n 1930) i Donora,
S.U.A. (樽n 1948), precum i de la Londra (樽n 1952).
De exemplu, pe valea Meusei, afluent al Rhinului, 樽n sectorul belgian
dintre localit釘ile Huy i Seraing ( circa 25 km), mrginit de coline ce
domin valea cu 75-100 m i dotat cu 樽ntreprinderi industriale ce se 釘in lan釘
(cocserii, combinate siderurgice, centrale electrice, fabrici de sticl, de acid
sulfuric, de 樽ngrminte chimice, etc), o cea釘 dens i persistent ( timp de
15 zile) a provocat, 樽n decembrie 1930, moartea a 60 de persoane i
simptome de otrvire la c但teva mii de locuitori.
ntre 5 i 8 decembrie 1952, factorii climatici (cea釘a, calmul atmosferic
i inversiunea termic) au determinat o situa釘ie catastrofal la Londra. Ca
urmare a creterii brute a con釘inutului de anhidrid sulfuroas ( de peste 20
de ori) i de substan釘e solide aflate 樽n suspensie ( de trei p但n la zece ori mai
mare dec但t cea obinuit) etc., numrul deceselor provocate de faimosul
smog londonez a fost evaluat la 4 000, iar cel al persoanelor care au avut de
suferit, cu mult mai mare.
Accidentul produs la Bhopal, 樽n ziua de 3 decembrie 1984, prin
eliminarea accidental a unui gaz toxic ( izocianat de metil ), provenind de la
o uzin de pesticide, s-a soldat cu 6 500 de victime i 樽mbolnvirea altor 10
000 de persoane ( sterilitate, afec釘iuni respiratorii, surzenie temporar, etc.).
Despgubirile pltite de concernul interna釘ional Union Carbide s-au ridicat
la 15 miliarde de dolari, fiind astfel cea mai mare sum 樽nregistrat p但n
acum 樽n asemenea cazuri.
Accidentul de la Seveso a avut loc la 10 iulie 1976, c但nd 樽n urma
exploziei unui reactor de la uzina chimic din localitate s-a scurs o mare
cantitate de dioxin, una dintre cele mai toxice i periculoase toxine, care a
semnat moarte, maladii i dezolare 樽n toat valea Brianza, 樽n care se afl
2. oraul 樽n cauz. Acest accident a fost un puternic semnal de alarm,
Comunitatea Economic European ( actuala Uniune European ) adopt但nd
樽n 1982 Directiva Seveso, care inventariaz 80 de substan釘e chimice
considerate toxice i a cror producere i stocare sunt supuse unor
reglementri cu totul speciale.
Nu mai pu釘in periculoase sunt incendiile industriale ( de genul celor de
la platforma petrolier Bravo din zcm但ntul norvegian Ekofisk din Marea
Nordului, 樽n 1977, de la depozitul uzinei chimice din Basel, Elve釘ia, 樽n anul
1986 .a.) sau haldele de steril din apropierea unor uzine metalurgice, de
ciment ori a exploatrii miniere. Ca urmare a pierderii stabilit釘ii haldelor, pe
acestea se produc alunecri, care se revars peste construc釘iile din apropiere,
nu de pu釘ine ori afect但nd chiar coli.
Hazardele nucleare sunt produse de rsp但ndirea necontrolat a unor
substan釘e radioactive 樽n afara instala釘iilor nucleare i a dispozitivelor de
deeuri radioactive. Substan釘ele respective pot s iradieze popula釘ia i
mediul 樽nconjurtor i pot produce victime omeneti i pagube materiale.
Hazardele nucleare sunt legate de centralele atomoelectrice, de
instala釘iile nucleare din unele institute de cercetare tiin釘ific, de cderea pe
Pm但nt a unor sateli釘i artificiali cu propulsie nuclear, precum i de
transportul i depozitarea deeurilor radioactive.
Accidente la centrale nucleare:
12 decembrie 1952 la Chalk River, l但ng capitala canadian
Ottawa;
7 octombrie 1957: - la Windscale Pile No. 1, nord de Liverpool,
Marea Britanie, unde a fost afectat o suprafa釘 de 520 km2;
- 樽n
apropiere de Kyshtym, 樽n sudul Mun釘ilor Ural, fosta Uniune
Sovietic, soldat cu evacuarea a circa 10 000 de persoane;
1976, l但ng Greifswald, fosta R.D. German;
28 martie 1979, la Three Mile Island, l但ng Harrisburg,
Pennssylvania, S.U.A.;
3. 26 aprile 1986 la Cernob樽l .
Cel mai grav accident este cel 樽nregistrat 樽n fosta Uniune Sovietic, la
Cernob樽l, 樽n Ucraina. Explozia unui dintre cele patru reactoare ale centralei
nucleare, 樽n noaptea de 25-26 aprilie 1986, a pulverizat peste 1 000 tone din
cuvertura protectoare i o mare cantitate de substan釘e radioactive care
con釘ineau Iod 131 i Cesiu 137. Dintre consecin釘e amintim: muncitorii i
pompierii care au asigurat stingerea incendiului, grav iradia釘i, au murit 樽n
lunile urmtoare, au fost evacuate imediat 200 000 de persoane din
localit釘ile aflate pe o raz de 30 km; au fost iradiate circa un milion de
persoane. S-a produs o contaminare nu numai a Ucrainei, ci i a altor regiuni
ale Europei ( 樽ndeosebi Europa Central i Peninsula Scandinav) i,
totodat, pentru prima oar a avut loc i o contaminare transcontinental,
fiind afectate Alaska (S.U.A.) i Canada.
