Introduction

Lung cancer is a deadly form tumor that advances in the chest cavity. It is the leading cause of cancer deaths among both men and women in the United States. Due to the severity of respiratory complications posed by this medical complication, early diagnosis and treatment is essential. The discussion below is aimed to create enlightenment on the development and treatment of cancer. It also focuses on the current researches about this complication and outlines some of the proposed treatment approaches. For a fact, early diagnosis and treatment of lung cancer is essential since lack thereof results in death.

There are several uranium deposits in the area that the developer wishes to build the resort. For example, in the Maritimes Basin and the crystalline basement in the Atlantic part of Canada. There is an abundance of uranium in the sandstone that is similar to the deposits found in the ground in Texas and more throughout the western part of the United States. The acknowledgement of the severely weathered granitites beneath the unique Windsor area in the South Mountain Batholith does suggest a link to similar areas much like the Athabasca Basin in Saskatchewan. The area has a large ...

Question 1:

Ernest Rutherford is sometimes referred to as the “Father of Radioactivity”. Rutherford made many contributions to research into radioactivity and the nature of an atom. Outline his contributions. Rutherford contributed greatly towards the experimenting, studying and understanding of radioactivity, and the atom. His initial contribution was the discovery and definition of the electron. The Nobel laureate proposed the Rutherford atom model that replaced the Thompson model. This provided an excellent basis for future work into the studying of atoms, as well as, their physical and chemical properties. He was involved in research aimed at splitting the atom leading to ...

Question one

Ernest Rutherford made remarkable contributions towards radioactivity and the nature of the atom. He was the first man on earth to discover that atoms have a small nucleus that is charged and its surrounded by space which is circled by very tiny electrons. This was what became to be known as the planetary model or Rutherford model of the atom. Rutherford collaborated with Fredrick Soddy on research on transmutation of elements. The two researched in X-ray effects based on conductivity of gasses ("Ernest Rutherford: Father of nuclear science," 2014). This is where they came up with the ...

Ernest Rutherford and his contribution in radioactivity

Ernest Rutherford is termed as the Father of Radioactivity and nuclear science. Rutherford, who born in 1871 and passed on in 1937, discovered alpha and beta rays. He set forth the law of radioactive decay, identified the alpha particles as helium nuclei. Rutherford postulated the nuclear structure of an atom. His contribution to Radioactivity came from an experiment he demonstrated by firing alpha particles into gas atoms where few particles were seen to deflect. This implied a dense, positively changed central region of an atom contained an atomic mass (Dardo, 2004). Figure 1. Top: expected results, alpha particles passing ...

Question 1

Radioactivity is the process by which unstable isotopes of elements disintegrate in the nucleus to release energy in form of gamma rays, beta radiation and alpha radiation. The disintegration occurs as a result of the stability within the cell nucleus. Some isotopes of elements have non-balancing number of the protons as compared to the neutrons, as a result of the lack of balance between the negative and the positive charges in the nucleus; the nucleus becomes unstable and disintegrates. Radioactive radiation was first discovered by Henri Becquerel in 1896 as he was working on X-ray. By then the X-ray ...

Question 1

Ernest Rutherford One of the contributions of Ernest Rutherford includes the discovery that the Becquerel rays consisted of two different rays (Sears, 2015). The discovery of the two rays came about after Ernest Rutherford focused his attention on actual radiations that are emitted by radioactive substances. The experiment consisted of evaluations of radiations that were emitted from successively layered sheets of aluminum placed over a uranium compound. A distinction made in the two forms of rays was their penetrating power. According to Sears (2015), to be able to distinguish between the two forms of rays, Rutherford named the easily ...
