ALARA stands for As Low As Reasonably Achievable Becquerel (Bq) unit of radioactivity in the International System of Units, equal to one disintegration per second classic coherent scattering introduction where the matter in which a low-energy phantom is absorbed and released with its same energy frequency and wavelength but with a change of Direction Compton scattering interaction with matter in which a higher energy Phantom strikes a Loosely bound outer electron removing it from its sh...

RADIATION STATE TEST EXAM LATEST UPDATE GRADED A A X-ray machine after turning off still emits radicactivity due to a process known as the Compton effect. False The disintegration or breaking up of an radiation is called radioactive decay. True Old depleted radiography sources can be treated as ordinary trash and thrown in the garbage False The strength of a source is calied the activity The time required for one-half of the unstable atoms to decay is known as half-life The spread of radio...

AMMO Radiation Safety Exam with answers 2023/2024 Radioactivity - correct answer A spontaneous process characteristic of atoms with unstable nuclei in which the nucleus releases energy either as a particle with kinetic energy or as electromagnetic energy Parent - correct answer The original isotope prior to radioactive decay Daughter - correct answer The isotope after the transformation Decay/Disintegration - correct answer A given transformation, one parent/daughter tr...
