geometry. Procedure and Observations Part 1a): In the first part of the experiment the EGS code was configured to calculate the influence of voxel size and the number of photons on the amount of radiation dose deposited on a water phantom. A mono-energetic source of 2MeV with a radius of 2cm was chosen to be the particle beam. A trial with 1million particles incident on a water phantom at a voxel resolution of 1cm was simulated then another trial

The effect of mobile phone radiation on human health is the subject of recent interest and study‚ as a result of the enormous increase in mobile phone usage throughout the world (as of June 2009‚ there were more than 4.3 billion users worldwide). Mobile phones use electromagnetic in the microwave range. Other digital wireless systems‚ such as data communication networks‚ produce similar radiation. The WHO has classified mobile phone radiation on the IARC scale into Group 2B - possibly carcinogenic

The Nuclear Power Debate In 1953‚ nuclear energy was introduced into America as a cheap and efficient energy source‚ favoured in place of increasingly scarce fossil fuels which caused air pollution. Its initial use was welcomed by the general public‚ as it was hoped to lower the price of electricity‚ and utilise nuclear power for it’s potential as a resource‚ not a weapon. However‚ as people became aware of the long term dangers involved in storing nuclear waste‚ it’s use was criticised. Two

Chapter 4: Case Study: When radiation therapy kills. The concepts of ethics are illustrated in this chapter. Ethics is a concern of humans who have freedom of choice. Responsibility‚ accountability and liability are issues that are raised by radiation technology. In this case we see that the carelessness or laziness of the medical technician‚ the lack of training in the handling of the equipment (software)‚ also of the maintenance of the updates of the software can cause the life a person.

Nuclear Power and Its Uses At first nuclear power was only seen as a means of destruction but after World War II a major effort was made to apply nuclear energy to peacetime uses. Nuclear power if made when a nucleus of an atom is split to release a powerful burst of energy. Though technological advancements nuclear power now supplies us with new medical aids‚ a new power source and new ways to do scientific research. New medical advancements are being produced rapidly due to nuclear power. Nuclear

Nuclear weapons cause unimaginable death and destruction. Without a doubt‚ these are the most powerful weapons mankind has ever built. However‚ there is also a scientific side to this weaponry which Teddy Roosevelt may have indeed called very big sticks. Nuclear weapons work by releasing the enormous amounts of energy that are contained in the bonds of atoms. The bonds of atoms can be broken in two ways. The first way is by fission‚ and the second way is by fusion. Fission works by the splitting

Singh Abstract—In the present paper‚ an observation of electromagnetic radiation from base station antennas installed for various communication purposes has been done on the basis of equivalent isotropically radiated power (EIRP) calculations. For this purpose‚ a typical wireless communication site has been selected where GSM‚ CDMA‚ 3G/UMTS and WiMAX antennas are

It is true that many people have varying opinions about having nuclear power plants and developing nuclear energy. I‚ myself‚ see it as a good alternative source of energy while my brother sees it as a weapon for mass destruction. Nowadays‚ people are easily swayed by the reports of the media. Indeed‚ most of them are true but some of them tend to be a bit exaggerated. The article pointed
