PHY 114: Absorption of Nuclear Radiation Abstract: The purpose of this experiment was to determine the mass thickness attenuation factor for beta rays when they pass through polyethylene sheets of varying thicknesses. This was done by using an apparatus that measured the seven different intensities and then taking these values‚ putting them through a number of calculations and finally generating a graph of ln(I_corr) versus the thickness of the polyethylene sheets. Once this graph

Chapter II Light and Matter The Inner Workings of the Cosmos 2.4 The Distribution of Radiation All microscopic objects – fires‚ cubes‚ people‚ and stars – emit radiation at all times. They radiate because the microscopic charged particles in them are in constant random motion‚ and whenever charges change their state of motion‚ electromagnetic radiation is emitted. The temperature of an object is a direct measure of the amount of microscopic motion within it. The hotter the object

interconnecting wires are inconvenient‚ hazardous‚ or impossible. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods under consideration include electromagnetic radiation in the form of microwaves or lasers. Energy transfer and efficiency The general principle is that if a given oscillating amount of energy (for example alternating current from a wall outlet) is placed into a primary coil which is capacitively

The Sun and other stars give off a wide range of types of electromagnetic waves‚ which travel through space to Earth. Much of this radiation is stopped by Earth’s atmosphere and can only be detected by satellites in orbit outside the atmosphere. Electromagnetic Waves consist of oscillating electric and magnetic fields which can travel through a vacuum while all other type of waves need

What is electromagnetic radiation? Electromagnetic energy is a term used to describe all the different kinds of energies released into space by stars such as the Sun. These kinds of energies include some that you will recognize and some that will sound strange. They include: * Radio Waves * TV waves * Radar waves * Heat (infrared radiation) * Light * Ultraviolet Light (This is what causes Sunburns) * X-rays (Just like the kind you get at the doctor’s office) * Short waves

scientists give a bunch of types of radiation when they want to talk about them as a group. Radiation is energy that travels and spreads out as it goes‚ visible that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves‚ infrared and ultraviolet light‚ X-rays and gamma-rays. Hotter‚ more energetic objects and events create higher energy radiation than cool objects. Only extremely hot

According to the DSM-5 trauma is defined as “exposure to actual or threatened death‚ serious injury or sexual violation” (APA‚ 2013). The exposure must be as a result of either: direct experience the traumatic event‚ observed the traumatic event personally‚ learnt of a traumatic event that happened to a close family member or close friend‚ or experiences first-hand repeated or extreme exposure of traumatic event (not through pictures‚ media‚ television‚ or movies) (APA‚ 2013).

Chernobyl nuclear plant is one of the biggest disasters in history! It happened on April 26‚ 1986. It was a nuclear radiation disaster. About 4‚000 people died. All the survivors suffered from the radiation side affects for the rest of there lives. This also ruined the environment! The nuclear plant exploded exactly at 1:23 A.M. The explosion killed two people. Then radiation started pouring out of the reactor. There were 134 emergency workers that got involved trying to figure out how to
