    Due to the exposure to an enhanced level of radiation, astronauts could experience about 1 mSv/day in deep space. It is equal to the radiation strength taking an x-ray every day. There would be two different consequences of the exposure to the space radiation, the acute consequences and the delayed consequence. The acute consequence is determined by the amount and the type of the radiation exposure, which would cause damage to the central nervous system and death. Based on our animal experiment, biological damage to our central nerve system would only cause by the high-energy, heavy ions, which are similar to what we know with aging. The delayed consequence means that there’s a limitation of the radiation a human body can take during his lifetime. However, by estimation, stay in space on long-term mission over 500 days, astronauts may exposed above 1 Gy (1 Sv). The long term exposure would ultimately result…

    Essay On Non Lead Apron

    • 931 Words
    • 4 Pages

    Advancement in Radiation Protection: Non-Lead Apron People are exposed to radiation every day just by being alive on this earth. One receives approximately 3,000 µSv of ubiquitous background radiation a year, which means approximately 8.2 µSv per day (Howerton, Iannucci, 2012). This is known as background radiation and is caused by terrestrial, cosmic, and naturally occurring radon. On the other hand, during radiographic examination some degree of biological damage does occur during exposure,…

    floors inside their homes. There’s radiation found in food and water that are consumed by people on a day-to-day basis. It is found within the gases inside the Earth’s atmosphere, and from cosmic rays from space ("Radiation in Everyday Life"). Even the human body has radiation within the muscles, bones, and other tissues. Radiation is found all over the earth. There are two main types of radiation that make all this possible, ionizing radiation and nonionizing radiation ("Radiation Explained").…

    Introduction Our Sun produces enough energy in one second to sustain life on earth for millions of years. However, there is an energy far more powerful than our Sun that makes it pale in comparison. Gamma-ray Bursts (GRBs) are the most energetic type of light in the universe and produce more energy in one second than the sun will produce in its ten-billion year lifetime. These dramatically powerful energetic explosions often originate billions of light-years from Earth yet produce a light so…

    Essay On Big Bang Theory

    • 821 Words
    • 4 Pages

    The Big Bang Theory is the on-going explanation about how the universe began. The theory talks about the universe as we know it starting with a small originality, then expanding over the next 13.8 billion years to the universe we know of today. The phrase "Big Bang Theory" has been popular among astrophysicists for decades. The idea is that the universe began with an explosion more than 14 billion years ago, and many scientists also believe our universe and others, come from a “singularity”.…

    discovery in the 1960s of cosmic background radiation, interpreted as an 'echo ' of the Big Bang, was considered a confirmation of this idea and a proof that the Universe had an origin. One cannot imagine the Big Bang as the explosion of a piece of matter in the void. In the Big Bang not only matter and energy was concentrated, but also space and time, so there was no place 'outside ' the primeval fireball, nor any time 'before ' the Big Bang. Is space itself expanding as the Universe ages,…

    its original size in less than a second. The universe rapidly cooled, particles called quarks and gluons, protons, neutrons and electrons formed, creating the first atoms, hydrogen was the first element and continues to be years later, Gravity pulled together clouds of hydrogen to form the first stars. Stars made all the heavier elements through nuclear fusion, such as helium, carbon and oxygen. Furthermore, Gravity pulled stars together into galaxies. It would take thousands to millions of…
