Question:                                                                                                                                                                                                                                                                                                                                 20










                                       If dose rate at a particular distance from 192Ir radioactive source is 1000





                                            Sv/hr, calculate the thickness of lead required to reduce the dose rate





                                       to 1 Sv/hr. Given for 192Ir, TVL is 1.62 cm of lead.
