Physical and Environmental Effects of a Nuclear War :: science

Physical and Environmental Effects of a Nuclear War Imagine the heat of millions of degrees, the immediate destruction of thousands of acres, and the deaths of hundreds of thousands of lives. Now imagine all of that times a thousand. There you have a nuclear war, the explosion of a thousand or more nuclear bombs on the earth. That is what is estimated would be a nuclear war. All of that power packed in relatively small(considering the power they unleash) bombs. The results of a nuclear war would be devastating. It would be devastating to the health and lives of people, and to the environment in which we live. The world wouldn't fully recover for hundreds of years. How a nuclear weapon works In a modern nuclear bomb, commonly called a thermonuclear bomb or a H-bomb, fusion is the power behind the explosion and destruction. Fusion is the fusing of the nuclei of two atoms, which produces an extreme amount of energy(about 40 times that of a fission reaction). For fusion to occur, though, an extremely high temperature and pressure must first be reached, and this is achieved by fission(splitting of the nucleus of an atom). The detonation of a fusion weapon begins with the detonation of a conventional explosive that sets off a fission reaction explosion. Plutonium and uranium are used to create fission. The atoms fused are those of the isotopes of hydrogen, deuterium or tritium. The fusion and fission from a thermonuclear weapon result in large amounts of radiation that can be fatal to humans and animals and can also cause many other effects. Short-term physical effects One short-term effect of a nuclear war would, of course, be the deaths of millions of people. It has been estimated that an attack on U.S. populations centers by 100 one-megaton nuclear weapons would kill up to 20 percent of the population immediately through blast, heat, ground shock, and instant radiation effects. Also, and attack with 1,000 one-megaton nuclear weapons (which many say is more realistic than just 100 weapons) would destroy immediately almost half the U.S. population. Those that do survive the initial explosions would be far from out of the clear. Those estimates above do not include the additional deaths from fires, starvation, or the lethal fallout showering to the ground downwind of the explosion. Skin burns, acute radiation sickness(which includes nausea, vomiting, diarrhea, and fever), and noticeable blood changes are just a few of the effects of radiation on the body.

They were coming to get him, creeping through the undergrowth towards him. As they drew near he jumped up to run on, but tripped. He had been spotted. The savages drew in, their spears all pointing at him, moving around him as he stared up at them, chanting ‘Kill the pig. Cut his throat. Spill his blood.’ As the chanting got louder, and the spears nearer, he screamed. He woke up breathing heavily, covered in sweat, his hair adhering to his forehead. A nightmare. The same nightmare it always was. He was back on the island again. Except this time the officer hadn’t saved him, the savages had killed him. Ralph sat up haltingly and went to fetch a glass of water. He checked his watch, six forty-five in the morning. No point going back to bed now, his appointment was at seven thirty. He knew why the dream had come back this time. Today he was going to meet Jack Merridew for the first time in fifteen years. As they stood outside the door the psychiatrist quickly briefed Ralph before he entered. â€Å"Remember everything we’ve talked about. This is for you to sort out what happened. To sort out, if you can, why it happened. Let the anger out. Don’t let him intimidate you into not saying anything.† Ralph entered the room alone. Jack was already there silhouetted against the window. He turned and surveyed Ralph as he entered, holding out his hand in greeting. Ralph was tall and thin with fair hair. Jack was bigger and looked stronger, with brown hair and dark eyes. They shook hands confidently, and then Ralph stepped back and was opening his mouth to speak when Jack began. â€Å"We both know why we’re here, don’t we. You want answers and I’m to give them to you. So here you are. When we arrived on that island, I believed that I would be leader, that I would lead everyone, just as I had led the choir. Then you blew the conch, everyone was already there when we arrived and you were in control. I liked the look of you but I hated that you had found the conch, that you were always making the sensible suggestions. When you gave me the responsibility of looking after the fire and hunting I thought I’d show everyone that I could be just as powerful as you. Then I let the fire out. You and Piggy hated me for that. You lost your respect for me. So I had to gain it in another way, the beast. But the beast separated us even more. I then knew that there was no way I’d ever earn your respect so I tried to earn the respect of everyone else to show you that I could lead a tribe. I started my tribe and persuaded others to join me. Then to show you that we could live without you we invited you to our feast. Then the incident with Simon happened. You didn’t come back after that. I was in control, you and Piggy were on the other side of the island and we didn’t mention you. We had rocks ready in case you ever came, but we didn’t expect you to come. I thought that if you did you would be impressed with the idea of protection. But then you came. You came with the conch and tried to call a meeting, and I heard you talking to my tribe. Then Roger set off the rock that killed Piggy. That’s when I knew that you had to die. You confused everyone because you used to be their leader and they still respected you. So I organised the hunt. Anyone who wouldn’t hunt you would be hunted themselves. We hunted you all the way to the lagoon, I know that we would have killed you if that officer weren’t there. But luckily for you he was. I’m sorry we killed your friends but they had to die.† Throughout his speech Jack had stared out of the window, a dazed look in his eye, using his hands to emphasise what he was saying. But during that last sentence fire had returned to his eyes. He turned and Ralph was filled with a sudden terror. This was Jack as he remembered him, dark and murderous. â€Å"They had to die Ralph, and you had to die. You escaped then but finally you have returned to me. I agreed to this meeting so that I could finish off the episode on the island. You have to die now Ralph. You have to die.† As he finished speaking he advanced on Ralph, pulling a knife out of his pocket. A low chant emerged from his mouth. ‘Kill the beast. Cut his throat. Spill his blood.’ Ralph’s body slumped to the floor, blood oozing out of the mortal cut to his throat.

African American Health Care Analysis Cheryl Robinson Capella University CST5500 Multi-Cultural Issues in Health Care Crobinson82@capellauniversity.edu Dr. C Vaugh Abstract It is a clichà © of health education that programs and interventions will be more effective when they are culturally appropriate for the populations they serve. In practice, however, the strategies used to achieve cultural appropriateness vary widely. This paper briefly describes African American history and how it relates to health care services. It explains the culture, value and belief of African American when it involves health promotion and disease prevention. Some major health concerns and barriers are noted within the black communities and population†¦show more content†¦African-Americans value health education and health maintenance which suggests that they are interested in their health, and may be receptive to prevention and health promotion interventions. Prayer, spirituality and church are important to African-Americans and play a key role in the lives of many of their lives. African Americans have traditional health and illness beliefs. They also are known to use folk medicine; the folk healers are root workers. Some African Americans, particularly of Haitian background, may believe in sympathetic magic. Sympathetic magic assumes everything is interconnected and includes the practice of imitative and contagious magic. Contagious magic entails the belief that once an entity is physically connected to another, it can never be separated. This type of belief is seen in the practice of voodoo, when an individual will take a piece of the victim’s hair or fingernail and place a hex, which they believe will cause the person to become ill (Campinha-Bacote, 2009). Black American churches have been the most important social institution in the black community and serves as a center for health screening, promotion and counseling. Many blacks hold their church with high esteem, therefore being an important coping resource for the African Americana community. To African Americans God is thought to be the spiritual healer.Show MoreRelatedMinority Health Disparities : Type II Diabetes1742 Words   |  7 Pages Minority Health Disparities: Type II Diabetes in African Americans Shelby Peterson HLTH 236 – 501 Jeff Guidry Texas AM University April 14, 2015 Executive Summary Type II Diabetes in African Americans is a major health disparity that is growing every day and needs to be understood more.
