RADT 1200 Final Exam Questions and
Answers
Radon - Answer-The first decay product of radium is
1. Creation of unstable atoms. 2. production of free electrons. 3. creation of highly
reactive free radicles capable of producing substance poisonous to the cell. 4. creation
of new biologic molecules detrimental to the living cell. 5. injury to the cell that may
manifest itself as abnormal function or loss of function. - Answer-Consequences of
ionization in human cells include
optimization for radiation protection (ORP) - Answer-The term as low as reasonable
achievable (ALARA) is synonymous with the term
