using 50 curies of ir92 what would be the dose rate at 75 ft from the source
Consider a 15,000-Ci 60Co source which gives off gamma rays of 1.17 MeV and 1.33 MeV from each decay. Assume that the dose rate at a distance R (cm) from a source of strength C (Curies) emitting gamma energy E (MeV) for each disintegration is given by: Calculate the dose rate at 1 m from the source and the time to receive the 75 rad. (Ans. t=21 seconds)

The original intensity (dose) of an x-ray procedure was estimated to be 0.45 mGyt at a setting of 40 mAs and 75 kVp. If the kVp was increased to 80, what would the new intensity (dose) be
A radioactive source emits 2.4-MeV neutrons at the rate of 7773 neutrons per second. The number of atoms in the source is 2.38x10^9. What is the activity of the source, in nano-curies (nCi)?
5) An individual is 50 cm away from a radiation source and is exposed to 1000 Roentgens of radiation (not good). Assuming exposure to 111.1 Roentgens is the maximum dose that an individual may be exposed to without major adverse effects, what is the minimum safe distance from the radiation source? (4

At what rate is the between the = A kire 50 ft above the ground moucs horizontally at a speed of 44/5 esting and the horizontal decreasing when 100 if of string person stay in the same place. The string always has been let out? (The y make a Giraight line)
Problem 4 In the figure below there are 125 ft of 2-in pipe, 75 ft of 6-in pipe, and 150 ft of 3-in pipe, all cast iron. There are three 90° elbows and an open globe valve, all flanged. If the exit elevation is zero, what horsepower is extracted by the turbine when the flow rate is 0.16ft/s of water at 20°C? Elevation 100 ft 2 in Open globe Turbine 6 in 3 in Problem 4
The intensity of an unshielded I-131 source is 32mR/hr. If the source is put into a lead shield 30mm thick what would be the intensity on the outside of the shield? Assume your distance from the source has not changed. The HVL of lead for I-131 is 0.178cm. A technician is in an area for 10 minutes and the reading on an exposure meter is 5mR/hr. Determine the actual radiation dose received by the technician. The technician should not receive...
