Year 9 Science - Nuclear Radiation

radiation

The emission or transmission of energy in the form of waves or particles through space or through a material medium.

radioactive decay.

The process by which an unstable atomic nucleus loses energy by emitting radiation.

particle equations in the context of nuclear reactions

Equations that represent nuclear reactions using particle symbols, showing the transformation of elements and particles involved in radioactive decay.

how is radiation measured

using devices like Geiger counters, scintillation detectors, and dosimeters, which quantify the amount and type of radiation present.

Define radioactive half-life.

The time required for half of the radioactive atoms in a sample to decay.

What are some industrial uses of radiation?

Sterilization of medical equipment, gauging thickness of materials, and tracing leaks in pipelines.
