OCR H556
Suggested PAG activity — PAG 7 – Investigating ionising radiation / example: absorption of alpha, beta or gamma
OCR requires safe use of ionising radiation and detectors in PAG 7; absorption of alpha, beta or gamma is the specification example, and this shared resource uses supervised gamma absorption by lead.

Gamma absorption by lead
Measure lead sheets with Vernier callipers, collect repeated counts and determine attenuation and half-value thickness.
This simulation supports preparation and data-analysis practice. It does not replace carrying out real practical work.
