I can: -recognize the meaning of radioactive.

What is Quantum Mechanics ?. Quantum Mechanics describes the laws that govern the time evolution and the behaviour of any physical system. They are the laws of motion and incorporate the principles of relativity. . It explains the stability and identity of atoms – why are

Radiation Safety Training: Fundamentals. University of Alaska Fairbanks September 2019. Training Contents. Radiation safety fundamentals Types of radiation Terms and definitions The principle of ALARA Shielding Detection of radiation and contamination

1. Radioactivity. Clip. 2. 1 . Differentiate among alpha and beta particles and gamma radiation . 2 . Differentiate between fission and fusion . 3 . Explain the process half-life as related to radioactive decay .

How do you know how many atoms and how many elements are in a symbol equation?. CO 2. Tells you how many ELEMENTS there are (an easy way to do this is to count the capital letters). The number tells you how many ATOMS of each of that element there is. Have a go….

Chemistry Chapter 28. Section 28.1 Nuclear Radiation. Objectives: Discuss the processes of radioactivity and radioactive decay Characterize alpha, beta, and gamma radiation in terms of composition and penetrating power. Radioactivity.

Interaction of Radiation with Matter. MATTER. ATOM. An Atom can be defined as the smallest quantity of an element which can enter into a chemical reaction. All atoms of a particular element are chemically alike but they differ from the atoms of other elements.

Chapter 7 Notes. Nuclear Changes. Chapter 7.1 Notes. Nuclear radiation Alpha particles Beta particles Gamma rays Neutron emissions. Alpha particles- are positively charged particle, emitted by some radioactive nuclei, that consists of two protons and two neutrons.

Nuclear Cardiology: Myocardial Perfusion Studies and Ventriculography . Croft Stone Nuclear Medicine. Basics of MPI. Radionuclide injected at rest and/or stress Radionuclide taken up by myocardium and gamma rays emitted Rest images compared with stress images

Nuclear Chemistry – Radioactive Decay. The discovery of radiation. In 1896 Henri Becquerel made an important discovery.

Dear Science teacher/ instructor:

Radioactivity and ionizing radiation Ivan Polia ček. Radioactivity and ionizing radiation Ivan Polia ček. The aims of the lecture. atomic structure ionization ionization vs. excitation (low vs. high energy photon) production of ionizing radiation basic particles and their properties

Nuclear Chemistry. Chapter 21. Warm Up. Astatine – 210 goes through alpha decay, beta decay and alpha decay in that order to become stable. Write the reactions that represent this process. Goals for Nuclear Chem.

1. Radioactivity. Clip. 2. 1 . Differentiate among alpha and beta particles and gamma radiation . 2 . Differentiate between fission and fusion . 3 . Explain the process half-life as related to radioactive decay .

Table of Contents. Chapter: Atoms, Elements, and the Periodic Table. Section 1: Structure of Matter. Section 2: The Simplest Matter. Section 3: Compounds and Mixtures. Structure of Matter. 1. What is matter?. Matter is anything that has mass and takes up space.

Nuclear Changes. (This is the stuff that can make you glow in the dark….) 100 trillion watts of fusion power. 7.1 What is radioactivity?. Some elements, particularly those with very large nuclei (note those at the bottom of the Periodic table), tend to have an unstable nucleus.
