Nuclear medicine imagining devices :Imagining ,or producing pictures of the distribution of the radioactivity is the most important aspect of nuclear medicine.
Rectilinear scanner-It use a NaI(Tl) detectors.-Two images are made of the radiation distribution -It use a focused collimators-A few scanners have two detectors focusing each other.
Gamma camera- It produces an image while stationary.- It has a large NaI(Tl) scintillation crystal about 1 cm thick and 30 to 45 cm in diameter.- The scintillation are viewed through a light pipe by an array of 19 or 37 PTMs.- A computer can be used in conjunction with gamma camera to obtain quantitive information.- A parallel hole collimator is usually used with gamma camera
The Szilard-Chalmers Reaction
Q. What is an intrinsic semiconductor? Give any two examples. A) A semiconductor which is pure as well as contains no impurity is known as an intrinsic semiconductor. B) In
A monochromatic beam of unpolarised light is incident on a glass slab. The reflected ray is found to be purely plane polarized. Evaluate the angle between the reflected and the ref
Huygens' construction; Huygens' principle (C. Huygens): The mechanical propagation of any wave (exclusively, of light) is equal to supposing that each point on the wavefront b
A 250V, 50Hz single-phase supply feeds the following loads (i) incandescent lamps taking a current of 10A at unity power factor, (ii) fluorescent lamps taking 8A at a power
Q. A capacitor of capacitance 2 μF is in an ac circuit of frequency 1000 Hz. If the rms value of the applied emf is 10 V, find the effective current flowing through the circuit.
In a plot of photoelectric current versus anode potential, how does 1. The saturation current varies with anode potential for incident radiations of dissimilar frequencies but s
