Physics - Assignment Example There are certain standards set as to assert the safety standard of any nuclear power plant. The organization that regulates the policies around the globe is known as IAEA (International Atomic Energy Agency). This organization has set a certain benchmark; which are actually, major concerns of a nuclear reactor in any country of the world. Some on the concerns are: 1. Testing of emergency situations, if and when they happen. 2. Equipment and actions to adhere the consequences of such an emergency. 3. Probability calculations of units failing and their back-ups. 4. Examining the worst possible scenario and creating an emergency plan accordingly. 5. Actions taken, in the event of radiation emissions form the plant. 6. Proper training of the men working in these facilities. 7. Anti-earth quake and anti-flood systems, which have to be, installed (Hugh, 2011). Question 2 There are three types of radiation particles namely alpha, beta and gamma particle radiations. Alpha radiations have be en defined as helium nuclei, comprising of two protons and two neutrons. It is considered to be very stable. Beta radiations have been defined as fast moving electrons formed by nuclear decay, whereas gamma radiations are known to be high frequency, short wavelength electromagnetic radiation (Cheng et al, 2000). All three of these radiations have certain benefits and disadvantages. The disadvantage of alpha particle is that when it in inhaled, can cause damage to lungs and the respiratory system. Beta rays cause disorder in the molecular structure of humans, whereas gamma rays can directly damage the human tissue, since they are very high energy rays. Along with these disadvantages, there are some benefits as well. Alpha particles are used to detect smoke for engaging a fire alarm or water sprinkler. Beta particles are used to find thickness of aluminum foil, its variables and capable of treating cancer patients as well. Gamma radiations are used to locate flaws in pipes, other stee l products for leaks and the integrity of welds in them (Cheng et al, 2000). Medical benefits of radiations can be seen in the use of x-rays and treatment of cancer, whereas non-medical use of radiation can be seen in industries, for detection of leaks and welding faults in different metal mediums. Also for non-medical use, the rays are used for inspection on the production line to check emptiness or the thickness of materials like aluminum. (Cheng et al, 2000). Question 3 Apart from nuclear power, there are other ways to produce energy like hydroelectric, fossil fuel burning, solar and wind power. All these methods have a lot of advantages and disadvantages. Some of them will be depicted here. Hydroelectric power is free of cost, as water flow is easily available all around the world but the drawback is the amount of expenditure involved to build dams and huge water turbines. Furthermore, the environmental hazard for hydroelectric power generation is the disturbance of the ecologic al habitat of the aquatic life in the region. Fossil fuel is the best form of energy as it provides predictable and a constant power source but the major drawback falters this form of energy. It is the fossil fuel that is not a reusable or renewable source and is becoming scarce from the world at a very rapid rate. Solar and wind power both have almost the same kind of advantage and disadvantage. The setup for both is very expensive and is unpredictable in nature but the best advantage of these sources of power is
