Alpha, Beta and Gamma Radiation

Introduction
 

Radioactive substances emit three main types of ionising radiation: alpha, beta and gamma. Each type has different properties, levels of ionising power and penetrating ability. Understanding these differences is essential for explaining radioactive decay, nuclear equations and the safe use of radioactive materials in medicine, industry and scientific research.

Success Stories

Gurpreet S

Claire T.

With Sarah's help my daughter managed to gain an A* in her Physics A Level exams (almost 100% on paper 2!) and was able to gain entry to UCL. We are so proud and cannot thank Sarah enough.

Sarah transformed my daughter's approach to Physics. Her examiner insight was invaluable for boosting her final GCSE grade from a 7 to a 9.
