At 8:00 a.m., a patient receives a 1.5-mg dose of I-131 to treatthyroid cancer. If the nuclide has a half-life of eight days, whatmass of the nuclide remains in the patient at 5:00 p.m. the nextday? (Assume no excretion of the nuclide from the body

Which nuclide has the greatest relative binding energy?   Question 14 options:   1H   59Co   238U

Please send me the question in 20 minutes it's very urgent plz

At 8:00 a.m., a patient receives a 58-mg dose of I-131 to obtain an image of her thyroid. If the nuclide has a half-life of 8 days, what mass of the nuclide remains in the patient at 5:00 p.m. the next day? (Assume no excretion of the nuclide from the body.)

Radiation workers enter an area for 20 minutes in which they are subjected to 50 keV neutron radiation at a dose rate of 10-6 Gy/hr. What dose in mSv do they receive? What is the initial activity of a 5 g radioactive source of 60Co given that the specific activity of 6⁰Co is 4.8 x 1016 Bq/kg? How many decays per second does this correspond to? After twenty years what activity does this source still provide if 6⁰Co has a half life of 5.3 years? What is the initial intensity, I, of the 5 g 6⁰Co source at a distance of 1m if the gamma rays emitted by 60Co have an average energy of 1.9 x 10-1³ J? What thickness of lead would be necessary to reduce the intensity of the radiation by a factor of 10 at this distance if the absorption coefficient of lead to gamma is 0.9 cm-¹? If the source was changed to one from which the gamma rays had an energy of 0.6 x 10-13 J, what thickness of lead would be necessary to reduce the intensity of the radiation by a factor of 10? Look at graph on slide 27 and…
