Q1 We have naturally occurring radioactive material with thechemical formula (Ce,La,Nd,Th)(PO4,SiO4). A sample of the ore ismined and is concentrated to 5%, 10%, 25% and 100% monazite So foursamples are created in 5%, 10%, 25% and 100% of this monazite.
a. Calculate the activity of the samples. Thorium 232 with aknown half life in literature should be used in activitycalculations.
b. would activity be different if the samples with 10% and 25%were dissolved in acids or other minerals? assume samepercentages.
show all steps for the question to be worth any marks the resultshould be given in Bq/gram thorium 232 half life is publicinformation and it should be used in this case.
