The Radiation Exposure For Astronauts

The Van Allen Radiation belt would have been too strong for the astronauts to pass at the time the first moon landing occurred. The Van Allen Radiation belt is a doughnut region in space in which the Earth’s magnetic field traps a high amount of protons and electrons carrying a high amount of energy. Conspirators believe that it would have been impossible for the Apollo astronauts to pass through the Van Allen Radiation belts because the radiation would be too strong for astronauts to pass through the time the first moon landing occurred (Millis). NASA claims, “the Apollo astronauts passed through the Van Allen belts too quickly to be exposed to dangerous levels of radiation” (Griggs). Also, NASA proves, “the radiation would be about 2,500 rem per year with almost no shielding. Considering how quickly the astronauts passed through the belts, they only would have been exposed to about 0.05 rem during the trip there and back” (Millis). Although the radiation levels were safe to pass through, it is proven that the U.S. did not have the right technology and proper shielding at the time to keep the astronaut’s safe while passing the belt allowing American’s to believe the moon landing was a hoax (Griggs).

Apollo 13 is a movie where many questions were left unanswered. That could possibly be that the director wanted us to know what the astronauts knew to to make it more realistic. This movie uses astronomy and problem solving to solve many of these unanswered questions. In this essay I will be discussing the following issues; How the astronauts found out about the explosion, some of the problems that came with the explosion, whether it is worth the risk to send humans into space, and what knowledge we have gained by going into space.

In the four texts of the 1969 Apollo 11 mission in which it discusses the landing of the first humans on the moon, the texts were from Times of London, William Safire, novelist Ayn Rand, and Herblock. The head of the mission Apollo 11, was Neil Armstrong. Neil took a colleague named Edwin Colleague. The whole world was watching this tremendous event that shocked the world. President Nixon was seen as a powerful leader to have held and arrange such a suspense, horrific event. In the first text, “Man Takes First Step on the Moon”, by the Times, gives the perspective of Neil Armstrong and how all the leader around the world have given respect to the US for being the first to make it to the moon. The second text, “In the Event of Moon Disaster”, by William Safire, it gives the view of the people seeing the astronauts as heroes. In the third text, “ The July 16, 1969, Launch: A Symbol of Man's Greatness”, by Ayn Rand, is based on the perspective of a NASA guide. In the illustration of the cartoon, ”Transported”, by Herblock, shows the reality of society in the time of chaos. The rhetorical appeals, pathos, ethos, and logos are used in these texts to attempt to achieve its purpose.

For starters, many conspiracy theorists question how the astronauts survived the Van Allen belts. The Van Allen belts are two large bands of radiation and, supposedly, it is claimed that humans wouldn’t be able to survive such amounts of radiation. If someone has been exposed to around 200 to 1000 ‘rads’ of radiation within a few hours,

This investigation will explore the question: How did the Space Race impact the Cold War? The years 1957 to 1969 will be the focus of the investigation, to analyze the Space Race during the Cold War, as well as how the USSR and NASA both reacted to it.

Beginning with the accident at Three Mile Island in 1979, a widespread belief has proliferated that all levels of ionizing radiation are dangerous. Since 1980, radiation hormesis studies have shown there is actually a threshold of danger with high level exposures, but below that threshold low dose radiation is essentially safe and quite possibly beneficial to life. Yet, this relatively new, seemingly contradictory understanding of radiation's health effects has gone essentially unknown to the general public. In order to grasp the reasons why, we must again return to the bombing of Hiroshima and Nagasaki.

Cold war, tensions were further aggravated when the Soviet Union sent the first human into space in April and resumed atmospheric nuclear test in September (Fitzgerald P. 4).

The Space Race was one of the biggest rivalries between America and the Soviet Union in the 1950’s to the 1970’s. The Space Race was part of something bigger, the Cold War. The Cold War was a time of political and military tension after World War 2, between different powers all over the world, but mainly between the U.S and the Soviet Russia. When people think of the Cold War, one of the many things that come to mind is the Space Race. In this essay I will write mainly about the Space Race and how both countries spent time and money building rockets and other devices. I will also talk about the steps it took to make it to the Moon. And lastly, the effects it had on American politics.

Do you remember when you were a little kid and you dreamed about exploring the stars? Imagine if when you grow up not only are you an astronaut but you were also competing to be the first to travel the galaxy. During the 1950s to the 1970s this was the case for the astronauts in the United States of America and the Soviet Union. The United States of America and the Soviet Union competed to be the first ones to explore space. All of the hostilities were thanks to the Cold War a war of words and ideas between the U.S.S.R. and the U.S.A. that lasted from 1948-1991. In this essay, I will write about one of the events in the Cold War – The Space Race: how it started, how people reacted, and who won the long lasting competition.

In an era of great pain and suffering for families of the United States, the 60s, one man whom the people admired, set out to seek support for a huge adventure, where only one truth was known at the time of the rally. Great uncertainty lies ahead for putting a man on the moon but the taks must be taken on as fast as a speeding rocket. The space race is one that President Kennedy did not want to lose.

On October 4th, 1957 the simple action of launching a beachball-sized hunk of metal into our orbit, reshaped the lives of people in the United States and across the world for the next years to come. This small ball of metal was Sputnik, a Soviet satellite with a radio transmitter inside letting out a small “beeping” sound. This object, as unsophisticated as it was, had the power to set the entire country into panic. To US officials this action not only made it clear that the Soviet superpower of Russia was more technologically advanced, but for all we knew they could be putting nuclear warfare into space. To the US this thought was unbearable, and because of this it would go on to set off a race of the century, the Space Race. A race to put technology into space, a race that would change American life at home and in foreign policy. From changes within the school system, to the Red Scare, life would be changed drastically in the years to come, not only in the U.S, but in Russia as well.

The 13 million people who live along the United States - Mexican border1 face unique health issues and disparities than their northern and southern residing counterparts. Access to health care is a great health determiner for the many foreign-born residents living in the United States, especially for undocumented immigrants2. The topic to be addressed in this review will include current health issues and accessibility of care for the people living along the US – Mexico border. This study will include infectious diseases, substance abuse as well as issues facing women and children. The combination of many social factors including increased poverty and drug use, limited healthcare and low self-efficacy are all impacting the rates of

Americans soon became worried, as it was close to the beginning of what would become to be known as the Cold War, of the fact that if the Soviet Union was in possession of missiles as powerful as the one used to launch the Sputnik mission (Balogh 14). As many feared, what was stopping them from using a similar missile on the United States in the event of political adversity? Likewise, during the beginning of the space race, there was a general lack of understanding behind the science of space. Many were enthusiastic for the new adventure, but even more knew nothing about space except what they had learned in science fiction novels and films (Engdahl 180). A combination of this fear of the Soviet Union’s missile capacity and a general dubiety regarding space exploration led to diverse opinions regarding America’s involvement in the space

The effects of radiation can be hazardous to any part of the human body. In this guide I will explain the advantages, and disadvantages of x-ray radiation. I will also discuss the technological advances that we have today then of what we had the past on the human body during radiation exposure. I will explain preventions of exposure and safety precautions that we as dental assistants as well as patients can follow to stay safe.

While healthy babies are born every day, not everyone is so fortunate. In many cases, diagnostic radiology is required for patients during their childhood. Can having this radiation during the formative years lead to adverse effects later in life? The biggest concern from radiation is the risk of cancer. Cancer can occur at any dose from ionizing radiation because it is a stochastic effect, meaning that it is probabilistic. The probability of a stochastic effect, such as cancer, increases as the dose increases. While receiving this radiation may be necessary, it can cause some serious trouble later in life, such as breast cancer, leukemia, and thyroid cancer.
