Co60 In the Nuclear Physics: Gamma Radiation (NPT) experiment we used C060 as the gamma source, with Aluminium as the absorber. Cobo also omits beta radiation of around 0.32 Mev. Recall that the no absorber thickness counts didn't fit with the rest of the data. How many 16 mm thick Al plates does it take to stop all the beta radiation from reaching the GM tube? Look up the CSOA range for beta radiation of 0.3 MeV energy in Al on the NIST ESTAR database. Convert from the px (g/cm) value given to the distance x in cm. Thickness of Al required to stop 0.3 Mev betas: * = 178 x cm X Mev. So after you put one plate in, In fact we see from the ESTAR database that one Al plate of 0.16 cm should stop betas of up to energy 032 only gammas are detected by the GMtube. 2nd part Convert 0.16 cm to px (alm), What energy is closest to this CSDA range in the table?
