Observing Nuclear Radiation

Notes

• The basic structure of an atomis a small central nucleus, made up of protons and neutrons, surrounded by electrons.
• The nuclei of radioactive substances are unstable. They bcome stable by radioactive decay. In this process, they emit radiation and turn into other elements.
• The three types of radiation emitted are: alpha radiation; beta radiation; gamma radiation.
• We cannot predict when an unstable…
