CHAPTER 1 INTRODUCTION Background of the Study Protecting the patient from unnecessary radiation exposure include not only the Cardinal Principles of radiation protection‚ but also the behaviors of imaging personnel towards each patient. It is often asked‚ "Why do we need to discuss patient protection when it is the patient who is being imaged and therefore being exposed to radiation?" "And is not all radiation exposure made within safe limits so that patient protection is not really possible?" The

THE NEGATIVE PHYSICAL EFFECTS OF NUCLEAR RADIATION Page 1 Abstract Nuclear radiation has been a major problem since 1941 when the Second World War began. A major contribution to World War Two is the nuclear bomb‚ also known as the Atom bomb. Once the two bombs were dropped‚ the usually terminal Leukemia was derived throughout Japan. There are three types of radiation‚ Alpha‚ Beta‚ and Gamma radiation. In my study of radiation I discovered that radiation can damage many cells in your body

THE EFFECT OF PAPAYA EXTRACT IN SEED GERMINATION OF MONGO SEEDS I. INTRODUCTION The angiosperm‚ or flowering-plants‚ from the Greek word Angein means vessel or receptacle‚ makes up the most adundant and dominant group in the kingdom plantae. From grasses to cacti‚ from tiny herbs and wild flowers to large maple trees and oaks‚ considering all plants familiar to you are majority belongs to these group. (Moses‚ P.B.‚ Chua N-H‚ 1988) In angiosperms‚ flower is the crucial site where sexual reproduction

Effects of Rapid Population Growth While population growth is at times a beneficial thing for a species‚ there are many factors that define when growth becomes detrimental. When population growth becomes "rapid" there is a great chance that the counter-productive level has been reached. The most accurate index is the balance between population and sustainability. 1. Rapid Growth o Rapid growth is a quick increase in population. The number concerned when calculating the population is the number

percentage. Ranking was used in the study for comparative purpose and for sharing of items analyzed. 3. Weighted Mean Another statistical technique used by the researchers was the weighted mean. It was used to determine the average responses of the different options provided in the various parts of the survey questionnaire use. The method is used in conjunction with the Likert Scale. It was solved by the formula: X= ∑ ƒx/n Where x= weighted mean ∑ ƒx= the sum of all the product of ƒ and x‚ ƒ being

Results The above results show the data collected after a week of measuring the biggest plant per bag. Each day the biggest radish plant in site A was measured and by day five the largest plant was 5 centimeters long‚ and had developed small green leaves. By the 5th day site B and D’s seeds showed no signs of growing and length remained at 0 centimeters. Site C and D’s superior seed both grew a total of 3 centimeters according to the 5th day measurements. Both the graph and table display the same results

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

radiation We can classify radiation into ionizing and non-ionizing radiation‚ according to the effects it produces on matter. Ionizing radiation includes cosmic rays‚ X rays and the radiation from radioactive materials. Non-ionizing radiation includes ultraviolet light‚ radiant heat‚ radio waves and microwaves.In medical practice ultrasound and magnetic resonance imaging (MRI) involve non-ionizing radiation. +light n heat radiation produced by the sun *ionizing radiation is produced by some
