• Beta particles can penetrate a few millimeters of aluminum • Beta decay itself comes in two kinds: β+ and β-. • β- emission occurs by the transformation of one of the nucleus’s neutrons into a proton, an electron and an antineutrino. • β+ decays is a similar process, but involves a proton changing into a neutron, a positron and a neutrino.

Source of Radiation Exposure 12% 0% 5% 3% 37% 36% 2% Cosmic Terestial Radon and Thoron Internal 5% Cosumer Produce Medical Procedures Nuclear Medicine Work

Uses For Radiation Medical Use Academic and Science Application Industrial Uses Nuclear Power Plants Medical exposed 7/10 Understand the important Kill germs without harming the substance Affordable source of electricity Kill cancerous tissue, reduce the size of a tumor, or reduce pain Effects on the environment Agricultural industry: food production and packaging trapped in uranium fuel pellets or in sealed metal fuel rods X-rays or radiation therapy Engineers use gauges Carbon Dating: age of containing radioactive a fossil substances to measure thickness Use about one-third of our energy resources to produce electricity

Famous Nuclear Disaster • March 2011, caused earthquake, then tsunami – 160, 000 people were forced to evacuate in the first days • Released celsium-134 and 137 – Including other volatile radioactive elements – Only 12% has decayed since 2011 • Company TEPCO – Meaning TEPCO – Utility company operates plant – Reduce contaminated ocean water Figure 5 - Fukushima explosion https: //permaculturenews. org/2013/10/01/the-worldmust-take-charge-at-fukushima/
