CHAPTER 3 NEUROSCIENCE CHAPTER LEARNING OBJECTIVES 1. Understand the key methods that scientists use to learn about brain anatomy and functioning. • Neuroscientists examine autopsy tissue and patients with localized brain damage to learn about brain anatomy and brain function. • EEGs and neuroimaging, such as PET scans and fMRI, allow scientists to study brain function in the living brain. 2. Describe the two major types of cells in the nervous system and describe the prima...

Where are x-rays made? - Answer-in the electron shell structure of an atom What is Bremsstrahlung radiation? - Answer-energetic electrons pass very near the nucleus of an atom. The strong forces of th positive charged atom causes the negatively charged electron to decelerate; the path of the electron is changed, and some of the kinetic energy of the electron is lost, and converted into x-rays what is characteristic x-ray radiation? - Answer-following the ionization of an atom that leaves...

Lesson Description Often the most neglected and misunderstood types of monitoring on hazardous waste sites are radiation hazards and monitoring. Therefore, waste site workers should understand radiation hazards and different types of radiation. This Radiological Hazards lesson introduces radiological hazards to help workers to choose the type of protection necessary for any type of radiation hazard they may encounter in the workplace. It categorizes radiation types and examines radiation dos...
