Radiation

Initial radiation was exposed approximately one minute from the explosion. Residual radiation stayed in the air and soil, even after a long period of time after the explosion. Radiation is measured in grays. Anyone receiving more than 7 grays of radiation will have no chance of surviving. (Skaer, 1998) There are around 400 deaths among exposed survivors in the next 30 years following the explosion, due to radiation-induced cancers and leukaemia. Among pregnant…

with good intentions, but in so doing, he may have doomed himself. In 1896, radioactivity was discovered by Henri Becquerel (Nobelprize.org). Upon its discovery, scientists started experiments on it, eager to learn everything they could about it. Radiation was experimented with by numerous scientists, one of the most well known of these, being Madame Curie. She spent her life studying radium,…

recalls “I can still see the bright-crimson glow, it was like the reactor was glowing. This wasn 't any ordinary fire, it was some sort of shining.” During the night graphite reactor number 4 had exploded and was releasing seven tons of dangerous radiation into the surrounding area (Borrero).…

weapons and the potential effects of radiation. As a result, both the United States and the Soviet Union conducted various experiments to study the impact of radiation on humans and military equipment. These experiments ranged from testing the effects of radiation on animals, children, and the elderly and to exposing military personnel. The government poorly kept the research documents safe, due to it being 50-20…

to death (Walston JD. 2012, Goljanek-Whysall K et al. 2016). In addition, the application of radiation to skeletal muscle has also been shown to alter the response to overload and impair regenerative processes (Gulati AK. 1987, Rosenblatt JD et al. 1992, Rosenblatt JD et al. 1994), even though due to the post-mitotic state of myofibers, it’s often mistakenly said that skeletal muscle is the most radiation resistant tissue in the body (Lewis RB. 1954, Khan MY. 1974).…

2. TITLE AND ABSTRACT 2.1 Title Radio frequency radiation exposure while using portable radios; awareness and educational training among fire fighters. 2.2 Abstract Fire fighters are issued with portable radios for communication when line of sight communications are impractical. On emergency incidents fire fighters use portable radios as primary communication source, without them controlling and managing these incidents would be impossible. This day to day use of the portable radio makes…

Radiation therapy uses high doses of radiation to kill cancerous cells and is sometimes used as a substitute for surgery, destroying or shrinking a tumor. Even though radiation therapy can save lives and prevent recurrence of cancer, healthy cells that are exposed to the radiation may develop into a new cancer (Radiation, 2014). Radiation can be internal or external. Internally, radiation is put inside the body near or in the cancer cells. Externally…

Although we lost many discoveries, we as humans continue to learn new information about the universe. This begins the discovery of radiation in 1912 by Victor Hess. Hess traveled at a high altitude in a hot air balloon and discovered that radiation was more intense when he was above than on the ground. But what Hess realized was the sun played no part in radiation above. Instead, it…

Many people are affected by leukemia. Leukemia is one of the most common cancers in children and teens. There are many types of leukemia that affect different people. The type of leukemia that most children are affected by is acute lymphoblastic leukemia. In this paper, I am going to discuss the definition and symptoms of acute lymphoblastic leukemia, the treatment of this disease, and how children are affected by acute lymphoblastic leukemia. (Acute Lymphocytic Leukemia) Acute lymphoblastic…

The sun constantly emits short wave radiation. This radiation can be dangerous to human health in large quantities, causing sunburn and skin cancers. Ozone (O3), another greenhouse gas, protects life on the surface by absorbing most of the damaging ultraviolet radiation from the sun. In order to maintain a radiative equilibrium, an equal amount of long wave radiation is released back into space. However, due to greenhouse gasses, not all of the terrestrial radiation makes it directly back to…
