Thermal radiation

Introduction Thermodynamics is an essential concept examined during the construction stage of houses, especially in the countries reaching extreme temperatures, such as Australia. By understanding the physics involved in thermodynamics throughout the construction stage of houses, such as heat transfer involving different colours and thicknesses, it is possible to re-examine the insulation of houses in hot countries. Such a report can lead to finding the most appropriate colour and thickness for…

heat can be transferred are called convection and conduction. Anything above -286 degrees Celsius gives off some amount of thermal energy, or infrared radiation. Half of the Sun’s energy is given off as infrared, and a good majority of the visible light gets absorbed, and then turned back into infrared radiation. Incandescent bulbs even give off 90% of their energy as IR radiation, and this is also true for toasters and other kitchen appliances. TV remotes use IR waves to send an invisible…

The Atomic Bomb Lighting the Way for Radiation Protection Even though radiation has been around since the beginning of time there was little known about it. When x-rays were discovered in 1895, radiation research followed suit right after. With Germany under Hitler’s reign, the Nazis began separating uranium to form the first atomic bomb to control the world. The push for the United States to be the first with the atomic bomb began with this knowledge. With the help of several scientists…

Introduction Radiation protection policy is distributed among several governmental Agencies in the United States. Each agency is tasked with controlling exposure to radiation and the safe use of radioactive materials and radiation generating devices. These agencies inform their policy with reports and recommendations from a number of organizations, including the National Council on Radiation Protection and Measurements (NCRP). The NCRP is a longstanding organization that strives to provide…

Applications of solar thermal and geothermal energies are integrated with the purpose of utilizing renewable resources in low-carbon, energy saving manners. Geothermal and solar thermal energies are both clean, renewable energies with a huge amount of resources that are viewed as sustainable sources of energy storage [4]. Solar thermal energy is recognized as one of the best long-term options for heating and cooling energy supply. It has benefits such as it always helps to reduce primary energy…

Today, 80% of the energy people use come from fossil fuels and about 1% comes from solar energy. This can be seen as not being a very practical use of energy sources since nonrenewable resources are limited. Renewable sources can be replenished and have a much smaller chance of running out than nonrenewable sources. Solar energy is one of the least used energy sources that people have access to in the world; it is also one mother Earth is relying on to save the nonrenewable fuels, such as coal.…

The Sun and Our Star - Have you ever questioned as to how and why we are able to dry our clothes in the summer, and to be able to heat food and treat our water? - This all thanks to the sun - Without the sun, we all would be dead, it gives us light, heat and energy to heat up the Earth - Most of the energy stays inside of the sun because of its gravitational pull, and all small amounts leave the surface in the form of radiant energy Type of star: Age: Yellow dwarf 4.5 Billion Years…

Humans may experience daily exposure to genotoxic chemicals. Exposure to these genotoxic chemicals is often inevitable because they can be found in any environment, from an individual’s home to his or her workplace. The exposure to genotoxic chemicals can eventually lead to high levels of DNA damage, which has been suspected of causing cancer. The DNA damage caused by these chemicals can be measured by sister chromatid exchange. Sister chromatid exchange is a sensitive biomarker that is used to…

Spectrophotometry is a method in which organic and inorganic substances are identified or characterized by the use of electromagnetic radiation. Electromagnetic radiation not only includes light (or photons), but thermal energy as well. While the electromagnetic spectrum consists of wavelengths between gamma radiation and the Far IR, most spectrophotometric methods rely on the UV and visible region. In order to use spectrophotometric methods, the sample being analyzed must be able to absorb the…

Solar energy is a radiant light and heat from the Sun harnessed using a range of ever-evolving technologies such as solar heating, solar thermal energy, etc .Solar energy is the best alternative energy resource for the Bronx because it 's is easily accessible. It also saves electricity, and it is a renewable source. However it may not be cost effective and cannot be used with weather other than sunny. Solar energy has multiple advantages, it also has disadvantages that can easily be fixed. One…
