Conduction‚ Convection‚ and Radiation Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers‚ Conduction‚ Convection‚ and Radiation. The first kind of heat transfer‚ conduction‚ is heat transferring through direct contact of materials. This would be the same thing as a pan on the stove. The heat from the stove touches the pan directly‚ therefore making the pan hot. The next type of heat transfer is convection

EFFECTS OF RADIATION Background Radiation is all around us. It is naturally present in our environment and has been since the birth of this planet. Consequently‚ life has evolved in an environment which has significant levels of ionizing radiation. It comes from outer space (cosmic)‚ the ground (terrestrial)‚ and even from within our own bodies. It is present in the air we breathe‚ the food we eat‚ the water we drink‚ and in the construction materials used to build our homes. Certain foods

Adaptive Radiation Adaptive radiation occurs most often in new environment with a variety of different unfilled niches so that plants and animals that are not adapted to those areas can exploit the resources in the respective niches. Once individuals begin exploiting the new niches‚ mutations that will benefit the species will spread throughout the population via natural selection giving the owners an overwhelming advantage over others without the mutation and throughout evolutionary time

Blackbody radiation is the electro-magnetic radiation emerging from a small hole in a perfectly black box containing electromagnetic radiation at a high temperature. Scientists were interested in setting standards for the electric and thus measured the distribution of the total electromagnetic energy in a black box among the different wavelengths of the light. But not until Max Planck‚ at the turn of the century‚ was a single mathematical formula for the observed distribution of the energy among

Brachytherapy (also known as internal radiation therapy) is the use of radioactive ‘seeds’ to help destroy cancerous cells. It is commonly used as a treatment for cervical‚ prostate‚ breast and skin cancer. How long the treatment will take will depend on where the tumor is and how large it is. Brachytherapy works from the inside of the body by placing the radioactive ‘seeds’ into the body next to the tumor. About 4/10 people with cancer have some type of radiation therapy as their treatment. History
