Radioactivity

Work done in this Nuffield 13 - 16 module followed from the D unit called ‘The Periodic Table’. This D unit provided enough material for eight double periods during a Further Science course and built on the content of the S units for Single Science. The teachers’ guide included seven worksheets to supplement the students’ booklet.

The teachers’ guide gave an outline of the regulations for the use of radioactive sources at the time of publications. The guide pointed out that the regulations change from time to time so that it was (and is) important to check against current guidelines before considering any of the demonstrations suggested.
