Chapter Six: Completing the Table…with a Bang 1. What is the difference between a “dirty” bomb and a conventional nuclear bomb? (1 mark) The difference between a “dirty” bomb and a conventional nuclear bomb is that a nuclear bomb is designed to destroy organisms using heat and impact, while a dirty bomb is designed to kill with gamma radiation. Radiation from dirty bombs, besides burning through skin, also alters the DNA in bone marrows, which significantly weakens the body’s immune system, and…

Natalie Caparelli Mrs.Stanton October 5, 2015 Is Nuclear Chemistry Worth The Risk? Pros and Cons of Nuclear Chemistry in Medicine Nuclear chemistry, along with its advantages, has many cons such as extended decay periods, emission of radioactive particles into the atmosphere, and negative side effects from its many medical uses. Radioactive particles vary in strength, alpha particles, for example, are able to pass through sheet of paper. On the other hand, gamma rays are about to pass through…

“All the Ares missions use Hermes to get to and from Mars. It’s really big and cost a lot so NASA only built one.” Pg 2. Hermes is the large spaceship used for the trip to Mars in the Ares 3 mission. It carries the Ares 3 crew from Earth to Mars’ orbit. “Hermes is powered by ion engines. They throw Argon out the back of the ship really fast to get a tiny amount of acceleration. The thing is, it doesn't take much reactant mass, so a little Argon (and a nuclear reactor to power things) let us…

Half-life Carbon dating is used to find the age of fossils, the earth, and rocks. 14C is an unstable isotope that causes radioactive decay. Because 14C causes radioactive decay, it is used in finding the age of organic matter, or the process of Carbon dating. Radioactive decay occurs when one element changes into another element as it decays. As 14C decays, it turns into 14N, an isotope of Nitrogen. Using the original amount of carbon in the organic material, and the half-life of carbon, 5,730…

Elements above the atomic number 95 are produced in a particle accelerator by accelerating a small charged nuclei (such as Helium, Boron or Carbon) in a particle accelerator to combine with a heavy nucleus (often of a previously made transuranic element) target. The transuranic elements have short half-lives as the atomic number increases. The smaller nuclei combines within the target nucleus, creating a new unstable nuclide or radioactive isotope. The high speeds are required to overcome the…

Radioactive decay occurs when the nucleus discharges an abundance of energy, in the type of waves, causing nuclear instability which can occur naturally or spontaneously. Alpha (α), beta (β), and gamma particles (γ) are the most known types of radioactive decay despite the fact that there are some more. Alpha decay, α, composes of two neutrons and two protons making alpha particles similar the nucleus of helium. Large components, for example, uranium, radium, and thorium have a greater number of…

Eighteen-thousand people lost their lives on March 11th, 2011 due to the triple disaster in Japan. An earthquake, tsunami, and three meltdowns caused the explosion of a nuclear power plant in Japan. The event was tragic, and out of the control of the workers at Fukushima Daiichi power. Despite certain exposure to radiation fifty brave and selfless workers stayed behind in efforts to control the devastating situation, and seven-hundred and fifty workers were evacuated. In addition to the 50…

Most individuals with even the most rudimentary knowledge of science have probably heard of x-rays and gamma radiation. Very few however, will be able to tell you where these forms of radiation come from. The answer: Pulsars. Pulsars, or neutron stars, are physics sandboxes that provide extreme conditions for humans to experiment with which are not readily available on Earth. Due to this usefulness, the discovery and research of these phenomena should be of the utmost importance. These neutron…

The experiment investigates a GM tube and a GM counter and the relationships of radiation. The experiment uses a GM tube to detect radiation coming from a source. This is done by the decay particle ionizing and causing the charge to build up in the tube, which is discharged and the discharge is counted by the counter and added to a display. The GM tube must be calibrated at the best voltage so that the count rate is independent of the voltage. A test was done to find this value by changing the…

atomic nucleus accompanied by energetic radiation. In this process the radioactive atomic nucleus also known as the mother nucleus transform into a daughter nucleus that may belong to another element. This daughter nucleus will often be radioactive and decay to a new daughter nucleus until it ends up with a stable nucleus. Isotopes are shortly, atoms of the same element but with a different mass number. They are defined as atoms of an element, which has the same number of protons but a different…
