Counter Radiation and the Greenhouse Effect As well as being warmed by shortwave radiation from the Sun‚ the Earth’s surface is significantly heated by the long wave radiation emitted by the atmosphere and absorbed by the ground. Let’s look at this in more detail. The energy flows between the surface‚ atmosphere‚ and space. Some of this radiation is reflected back to space‚ but much is absorbed‚ warming the surface. Meanwhile‚ the Earth’s surface emits long-wave radiation upwards. Some of

ABSTRACT The effect of different levels of radiation was determined using four set-ups-10kR‚ 30kR‚ 50 kR‚ and the control (no radiation). The four set-ups were observed for nine weeks and growth (in cm)‚ germination‚ and survival rate was measured. Results showed that at the right level of radiation level (10 kR)‚ radiation have a positive effect on the plant growth and has the same germination and survival rate from the control set up. The 30 kR set up and 50 kR set up are relatively smaller

“Solar Radiation and its Effects on Planet Earth” The Sun emits a tremendous amount of energy‚ in the form of electromagnetic radiation‚ into space. If we could somehow build a gigantic ball around the Sun that completely enclosed it‚ and lined that ball with perfectly efficient photovoltaic solar panels‚ we could capture all of that energy and convert it to electricity and be set in terms of Earth ’s energy needs for a very long time. Lacking such a fanciful sphere‚ most of the Sun ’s energy

Concepts of Radiation Radiation * Emission of energy from an atom and the transmission of this energy through space. * Energy propagated in a material medium or space. * Energy in transit. What are the types of radiation? * Radiation is of two general types in our environment. * They are called non-ionizing and ionizing. Ionization * the energy transferred to the electrons causes them to be pulled away or removed from an atom entirely. * The result is the

A single mother whose life has gone awry‚ she copes with it through self-hatred‚ cynicism‚ and drug abuse‚ and by verbally (and at times physically) abusing her two daughters But she finds other ways to sustain herself. There are many internal

Radiation Exposure Do you know much radiation you are exposed to everyday? Many people are not aware of the radiation levels around them on a daily basis. I believe that exposure to radiation should be minimal. I think protection and prevention is vital. Being aware of the health risks and what can be done to protect yourself should be a well known piece of knowledge. If followed‚ this knowledge can help reduce radiation exposure levels. Exposure to radiation is higher today than it has ever

The Biological Effects of Radiation Whether the source of radiation is natural or man made‚ whether it is a small dose of radiation or a large dose‚ there will be some biological effects. Radiation causes ionizations of atoms‚ which will affect molecules‚ which may affect cells‚ which may affect tissues‚ and so on. Although most people tend to think of biological effects in terms of the effect of radiation on living cells‚ in actuality‚ ionizing radiation‚ by definition‚ interacts only with

Gamma Rays in Radiotherapy 8B Lae Eun Kim In this unit‚ we learned that there are 7 types of radiation of the electromagnetic spectrum – gamma rays‚ x-rays‚ ultraviolet‚ visible spectrum‚ infrared‚ microwaves and radio waves. With different wavelengths‚ they each have different properties and uses. Gamma rays are the radiation with the smallest wavelengths – 10-12m to 10-10m – and the most energy and the most danger of any wave in the electromagnetic spectrum. Radiotherapy‚ a treatment the use

INTRODUCTION Radiation‚ flow of atomic and subatomic particles and of waves‚ such as those that characterize heat rays‚ light rays‚ and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation and the matter with which it interacts and describes how energy is transferred from radiation to its surroundings. Considerable attention is devoted to the consequences of such an energy
