Background radiation and correction

Background radiation and correction

Radioactivity is random for individual nuclei, but the count rate from a source can still be measured reliably over time. A GM tube still detects radiation when no source is present because background radiation is always around us.

  3. /α, β and γ radiation (A-level only)

Step-by-step lessons on AQA A Level Physics $\alpha$ , $\beta$ and $\gamma$ radiation (A-level only). Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
