Radioactive contamination

impact in the field of cancer, its impact on society and its pros and cons. “Cobalt was discovered in 1735 by a Swedish scientist named George Brandt. He demonstrated that a blue color common in colored glass was caused by a new element, cobalt. Radioactive cobalt-60 was discovered…

to identify if there was a relationship between distance from a radioactive source and its radioactivity. Within this radiation lab experiment, we put the following hypothesis to the test: If the distance from the source, in centimeters, is increased then the Ionizing Radiation does is expected to decrease because the radiation decreases as it gets farther away from the radiation emitter, due to the loss of energy from the radioactive particles as they move through the air. The hypothesis…

cancer whilst minimising the damage to other tissue. For curing cancer the radiation needs to be very carefully targeted and controlled, so the radiation is produced by a powerful X-ray machine. With internal radiation therapy, a small amount of radioactive…

Essentially, everything he did was a mistake. Bombing scenes are basically no different than other crime scenes in basic processing principles and procedures, many times on a larger scale Basic principles such as scene safety and security, scene documentation, evidence collection/processing, specialized equipment, witness and victim interviews, removal of human remains, and releasing the scene are all based on the same principles. Matt’s first mistake was “immediately” going straight to the…

Rhonda Moore Bio/ Lecture 1101 D957 October 2, 2016 Radioactive Dating A) Any method of determining the age of earth materials or objects of organic origin based on measurement of either short-lived radioactive elements or the amount of long-lived radioactive element plus its decay product. Example: B) Look at the diagram below which represents the radioactive decay of uranium- 238. The shaded area represents the decay product which is lead-206. The half…

Task 1: radioactive decay is a nuclei of some isotopes which are unstable. If a radioactive isotope decays the it will change and become a different atom with different number of protons. Radioactive decays also are a process which has an unstable atomic nucleus and which causes it to lose energy this because of radiation, for example there three main types of radioactive decay alpha, beta, and gamma particle. If a material has unstable nuclei it would be considered as radioactive. If an atom…

Method In this LAB we measured how long it would take for varying starting amounts of M&M’s to decay. We did this LAB in order to find out if the rate of decay is dependent upon the initial amount of mass present in a radioactive sample. We changed the starting number of M&Ms or the initial “mass” of the M&Ms (our independent variable) in order to be able to come with a clear answer to the question. We also controlled the number of times we would shake the cup in order to not change the way we…

The solutions to nuclear waste involve salt domes and new technology of nuclear power. The best option for storage of nuclear waste is to store it in salt domes. Salt is the “ultimate geologic medium for retention of radioactive material” this allows for the entrapment of the radiation and heat emitted from nuclear waste (Funderburk). Salt domes are also geologically stable for 50 to 100 million years which assures prevention of degradation of the storage facilities (Funderburk). Salt domes are…

“inhalation, ingestion or through the bloodstream”. External exposure can transpire by breathing in “airborne radioactive Material”. Other external sources to ionizing radiation are cause by medical radiation through the imaging department. This medical procedures include x-rays for diagnosing and treatment, and even research. Gamma rays are also use by medical doctors to create radioactive tracers, that allows them explore a patient’s body without having to perform surgery. Gamma rays are…

methods, physicians began testing the effects of the new elements in humans. Pioneering the experiments on human subjects in the field of nuclear medicine, Frederick Proescher used the knowledge from his predecessors to advance the medical use of radioactive materials. Changing the way that science understood the evolving field of nuclear medicine, Proescher became one of the first scientists to use radium for medical purposes. The medical experiments with radium allowed science to change…
