Ionizing radiation

There’s a little bit of background information to know about the Brassica lab, in order to fully understand what is being tested and the mechanisms behind it. There are questions that need to be asked such as: why use Wisconsin fast plants, what gamma radiation does to organisms on a molecular level, and even what it does to organisms on a physical level. Why did we use Wisconsin fast plants for this experiment? Wisconsin fast plants are more formally known as Brassica Rapa and are rapid…

Life, until now is known to be found only on earth. Although, life has travelled to space but it cannot survive there without the necessary induced conditions. Only lichen and mosses have survived the vacuum of space and UV radiations yet. Imagine if you could survive the space without these conditions! Tardigrade (Water Bear), a water dwelling, 8 legged, segmented micro-animal has survived the space without any protection. They are prevalent in mosses and lichen and have a lifespan of a year.…

patient’s brain CT, the IR (ME) R 2000 regulations were undoubtedly breached (DoH, 2012). The protocols are in place for ensuring patients’ safety during irradiation; overexposure is in violation of the legislation and could lead to symptoms of overdose radiation to the…

One of the most mysterious, yet terrifying realities of the modern world is the topic of atomic warfare. Not many people understand how it works, however they terrified of it as an imminent threat. A majority of people have the topic of atomic warfare hiding in the back of their heads but don’t think too much of it because it’s been years since a country has been attacked. A recent number of tests in North Korea has scared many Americans due to a history of tension between the two countries. The…

beam is shot at the patient twice as far away as it would originally be directed at the patient then it would quarter the dosage of radiation the radiographer receives but it would also cover a larger surface area. This would have a positive effect as the radiographer would be able to x-ray a larger part of the patient’s body but would not be affected by the x-ray radiation themselves.…

Why to Stop Nuclear Weapons Nuclear weapons are very destructive. They cause terrible damage to anything they hit and surrounding area. Although only two have been used in war the threat that more could be used is very possible. Many countries and terrorist groups are trying to get their hands on nuclear materials and weapons so that they can cause harm to other more powerful countries. How the weapon is made, what it is, its effects on the environment, treaties formed, nuclear security, and…

Imagine the severity of a nuclear explosion, and how detrimental it could be. This could be a reality for anyone. In the fictional short story “Grace Period” by Will Baker, a man is faced with this, as it soon becomes his reality. He first notices the expansion and contraction of the atmosphere. Then, the odd behaviour of his dog, when it is whining under the porch. Subsequently, he feels the shifts of the ground beneath him. He notices a invisible jet , and the streak of cloud following it.…

The type of scanner is a modality-dependent feature. For example, MRIs and CT scanners are differ in size and functions. In medical ultrasounds, patients are not required to enter a scanner to be tested for CAD. These intrinsic modality-dependent differences were therefore considered as important test-specific attributes. In a DCE on scanning modalities to diagnose focal liver lesions, the type of scanner used was studied and shown to influence patient preferences for diagnostic tests (Whitty et…

infancy, it was common practice for the dentist or dental assistant to help the patient hold the film in place while taking the radiograph, exposing them to unnecessary radiation, repetition of this endangered their health and occasionally led to permanent injury or death. Fortunately, although the hazards of prolonged exposure to radiation are not completely understood, scientists have learned how to reduce them drastically by proper use of fast film and digital sensors, safer x-ray machines,…

it is vital to discuss the harmful effects, ways to protect oneself from radiation exposure, and on going campaigns and studies that aim at increasing the awareness and safety of damaging rays. Radiation has a variety of negative effects ranging from early to late. Early effects…
