Background radiation

the different particle types by virtue of the pulse height distribution and establishing detection window threshold within the detection unit. As discussed earlier, it is possible to establish a lower threshold limit that eliminates pulses from background and noise. In addition establishing an upper threshold would determine a region where the majority of the beta pulses will be detected. This region will be identified at the Beta (βo) window. The dotted lines are the detection…

Conventional methods of teaching are loathed for their intention of manipulation & control. Having seen through something of ourselves that we do not seem to trust, Education itself is a process, where the subjects’ (students) potential is being stimulated; curiosity gets directed towards their self-actualizations. This can be achieved via a single approach that conducts teacher-centered teaching, alternatively doable via multiple approaches such as self-supervised learning, which seems…

Light is part of a continuum of radiation or energy waves and the relationship between light wavelength and energy is inversely proportional: the shorter the wavelength the greater the damage to living organisms caused by them (e.g. X-ray wavelength is between 0.03 and 3 nanometers while…

Every type of electromagnetic radiation travels at the speed of light (186,282 miles per second) through a vacuum. Everything on the electromagnetic spectrum is at a different wavelength. Only a small portion of the spectrum is visible light. Of that light, violet’s wavelength is the…

children with cancer. Children are more likely have to severe side effects from radiation than adults because children…

Dangers of Radiation. Soldiers have been put in danger throughout recent history due to negligence with nuclear material and weapons testing. Either through having soldiers being at the actual test sites when the bombs were detonated or having them complete military exercises afterwards or getting the site ready for the next weapons test. Having soldiers move around radioactive material, living on bases nearby radioactive material, getting unknowingly bombarded by radiation to see its effects…

When we think about light we think something that is visible to us. For example, the light that comes from a light bulb or your car headlights and the sun. But in fact, we are recognizing “white lights.” This is the light that is divided up into six elementary colors; red, orange, yellow, green, blue violet. This is true when you place a thick piece of glass in the sunlight and a rainbow band of colors appear. These colors are put onto a light spectrum with its shortest wavelength are violet…

A hero can be classified by many things. A hero can be superman, a police officer, and even your mom, but what makes a hero. Is it someone who can fly or shoot laser beams from their eyes or someone who saves a baby from a burning building. I’ll admit some of these characteristics are far-fetched since I don’t know anyone who can fly or randomly saves babies on a normal day. All heroes, including super ones all, have something in common, they're admired for their courage or an outstanding thing…

Physics: Analogy of Light and Sound Light and sound share many common aspects. Today, we will study some of notable similarities and differences between the two. We can perceive both light and sound. We see through eyes and hear through ears. Both light and sound are waves. Light is an electromagnetic wave whereas sound is a mechanical wave. Light is created by interaction of electric and magnetic field. It does not require any medium for propagation, so it can propagate in free space. On the…

3.4. Friction Characteristics of the NCD, MCD and boron doped NCD Coatings against Alumina Balls The friction coefficient curves of NCD, MCD and boron-doped diamond films sliding with Al2O3 balls are shown in figure 4, figure 5 and figure 6, respectively, for a sliding speed of 8 m/s and a load of 1N, 5N and 10N, respectively. Figure 4 (a), figure 5 (a) and figure 6 (a) show the friction coefficient of NCD, MCD and BDNCD at 1 N, respectively. Figure 4 (b), figure 5 (b) and figure 6 (b) show…
