Although the basics of physics, instrumentation, and radiobiology have not changed, their techno- logical applications have been changing and improving continually. Nuclear medicine professionals worldwide appreciate the book so much that the previous edition has been published in Japanese. Changes in content and appreciation of the book are the two guiding factors in writing this third edition. Like the previous editions, the book is aimed at residents taking the American Board of Nuclear Medicine, the American Board of Radiology (Physics part), and the American Board of Radiology with Special Com- petency in Nuclear Medicine examinations, and for the technologists taking the Nuclear Medicine Technology Certifying Board. The book contains 16 chapters, and at the end of each chapter, references and suggested readings have been updated and new questions have been added where appropriate. The ﬁrst 10 chapters have only minor changes because of the basic nature of the contents. A section on the chi-square test and evaluation of diagnostic tests has been added in Chapter 4. In Chapter 8, the section on scintillation detectors has been rearranged and the section on dead time has been expanded. In Chapter 10, the sections on uniformity, gamma camera tuning, and quality control tests have been revised. Chapter 15 has been expanded to include more information on cellular damage by radiation, and also a section on dirty bomb and radiation phobia.

These two entities are interchangeable and exist in different forms to make up all things visible or invisible in the universe. Whereas matter has a deﬁnite size, shape, and form, energy has different forms but no size and shape. Matter is characterized by its quantity, called the mass, and is composed of the smallest unit, the atom. In atomic physics, the unit of mass is the atomic mass unit (amu), which is equal to 1. Energy is the capacity to do work and can exist in several forms: kinetic energy (which is due to the motion of matter); potential energy (which is due to the position and conﬁguration of matter); thermal energy (which is due to the motion of atoms or molecules in matter); electrical energy (which is due to the ﬂow of electrons across an electric potential); chemical energy (which is due to chemical reaction); and radiation (energy in motion). Of all these forms, radiation is of great importance in nuclear medicine and, therefore, will be discussed in detail. Mass and energy are interchangeable, and one is created at the expense of the other. This relationship states that every- thing around us can be classiﬁed as matter or energy. Particulate radiations: Examples of these radiations are energetic elec- trons, protons, neutrons, a-particles, and so forth. The particulate radiations originate from radioactive decay, cosmic rays, nuclear reactions, and so forth. Electromagnetic radiations: These radiations are a form of energy in motion that does not have mass and charge and can propagate as either waves or discrete packets of energy, called the photons or quanta. Various examples of electromagnetic radiations include radio waves, visible light, heat waves, g-radiations, and so forth, and they differ from each other in wavelength and hence in energy. The energy of an electromagnetic radiation is given in electron volts (eV), which is deﬁned as the energy acquired by an electron when acceler- ated through a potential difference of 1 volt. The Atom For the purpose of this book, the atom can be considered as the smallest unit in the composition of matter. The atom is composed of a nucleus at the center and one or more electrons orbiting around the nucleus. The protons and neutrons are about 1836 times heavier than the electrons but the neutron is heavier than the proton by one electron mass (i. The number of electrons is equal to the number of protons, thus resulting in a neutral atom of an element. The size of the atom is about 10−8cm (called −13 the angstrom, Å), whereas the nucleus has the size of 10 cm (termed the 14 3 fermi, F). The elec- tronic arrangement determines the chemical properties of an element, whereas the nuclear structure dictates the stability and radioactive trans- formation of the atom. Electronic Structure of the Atom Several theories have been put forward to describe the electronic structure of the atom, among which the theory of Niels Bohr, proposed in 1913, is the most plausible one and still holds today. The Bohr’s atomic theory states that electrons rotate around the nucleus in discrete energy shells that are stationary and arranged in increasing order of energy. These shells are des- ignated as the K shell, L shell, M shell, N shell, and so forth. When an elec- tron jumps from the upper shell to the lower shell, the difference in energy between the two shells appears as electromagnetic radiations or photons. When an electron is raised from the lower shell to the upper shell, the energy difference is absorbed and must be supplied for the process to occur. The detailed description of the Bohr’s atomic structure is provided by the quantum theory in physics. According to this theory, each shell is des- ignated by a quantum number n, called the principal quantum number, and 4 1. Structure of Matter denoted by integers, for example, 1 for the K shell, 2 for the L shell, 3 for the M shell, 4 for the N shell, and 5 for the O shell.
In years past order genuine zudena online erectile dysfunction quitting smoking, this endeavour generic zudena 100mg otc erectile dysfunction caused by ssri, called posi- tional cloning, was a massive undertaking that often involved 1.

The diagram shows two possible ways a speciﬁc chromosome might segregate in a family in which hearing loss is being transmitted as an autosomal dominant trait. In Scenario 2, inheritance of the bold chromosome exactly parallels inheritance of hearing loss. If this happens sufﬁciently often, it would suggest that the hearing-loss gene is carried on that chromosome. However, in real life, pairs of chromosomes swap segments during each meiosis, so what we have to follow through the pedigree is a chromosomal segment rather than a whole chromosome. Understanding the genotype: basic concepts 13 Inevitably, it can go wrong in many different ways.
