In the Classroom. May/June 2013 issue . of . Radiologic . Technology. Instructions:. This presentation provides a framework for educators and students to use Directed Reading content published in . Knowledge of subatomic particles has led to many advancements- unfortunately besides the advancements in power plants there has been costs-nuclear warfare and waste. Nuclear Decay. The nucleus-cluster of protons and neutrons-is in the centre of an atom. . Emission and Absorption . Take away concepts. Conservation of energy. . Black body radiation principle. Emission wavelength and temperature (Wien’s Law). . Radiation vs. distance relation . Black body energy flux (Stefan-Boltzmann Law) . Learning Objectives. I must be able to recall when ionising radiation is emitted. . I should be able to describe the three types of ionising radiation.. I might be able to explain the dangers of ionising radiation.. Transfer of Energy as Heat. Energy moves as heat in three ways. Heat is always a transfer of energy from objects at a higher temperature to a lower temperature. There are 3 different ways this transfer of energy can happen. Biology. Rad T 290. Objectives – Radiation Biology. Radiosensitivity. Somatic Effects. Embryonic and Fetal Risks. Genetic Effects. Patient Interactions. **Photoelectric**. Classic Coherent Scatter. Radiation Safety/Protection. Medical diagnostic x-rays contribute more to the exposure of the population than do all other man-made sources of radiation. As an occupational radiation worker, you may be exposed to more radiation that the general public.. From Astronomy To Biomedicine. Light and Matter .  Spectroscopy. .

Radiation refers to the process that is concerned with the passage of energy between places through space. . It is the radiation generated by sun that . regulates the temperature of earth. . . CLASSIFICATION OF RADIATION: ionizing or non-ionizing types. . The cell life cycle The cell cycle G0 = Cell is resting G1 = RNA and proteins are made S = DNA is made G2 = Apparatus for mitosis is built M = Mitosis (the cell divides into 2 cells) G0 phase (restin
