A patient is being given a chest X-ray. The X-ray beam is turned on
for 0.20 s, and its intensity is 0.400 W/m². The area of the chest
being exposed is 0.0650 m², and the radiation is absorbed by 3.80
kg of tissue. The relative biological effectiveness (RBE) of the X-ray
for this tissue is 1.1. Calculate the biologically equivalent does
received by the patient.

You are hired as an expert witness by the attorney representing a doctor. The doctor is being sued by a patient who claimed radiation damage from the doctor’s x-ray machine. The plaintiff argues that the machine must not have been properly shielded, exposing him to dangerous radiation. Your visit to the doctor’s office shows the following results. You do indeed measure x-radiation in the doctor’s office, with a minimum wavelength of 30.0 pm. Consultation with the doctor and inspection of his x-ray machine shows that it accelerates electrons through a voltage of 35.0 kV before they strike the target, producing bremsstrahlung. What advice do you give the attorney?
Smugglers. Rumor has it that a company has been smuggling gold out of the country using sealed, cylindrical barrels with hollow walls.
They pour molten gold into the hollows, and then fill the remainder of the barrel's internal volume with packing peanuts. The total
mass of the gold-walled barrel was designed so that it exactly matches those used to transport a volatile chemical that cannot be
exposed to air (and therefore the barrel cannot be opened and checked). The X-ray machine usually used to screen containers is
suspiciously damaged and not available.
TUL
(a) There are 20 barrels total, and they are all identical: mass m = 50.0 kg, height h = 1.2 m, and diameter D = 0.25 m. How do you
determine which ones have walls filled with gold (and are essentially hollow on the interior except for packing peanuts) and those
completely filled with the volatile chemical (a tightly-packed powder) where the mass is uniformly distributed? Hint: apply the
concepts of moment of inertia.

The H line in the spectrum was found to be split into two lines, a high intensity line at 656.28 nm, and a low intensity line at 656.01 nm.
