Solid state simeconductor
It is main advantage is that it has much better resolution than NaI(Tl)It is main disadvantages are that it is not available in large sizes and it is much more expensive.
The principle of operation :its acts as a solid ionization chamber so it acts as an insulator and dose not allow current to flow until ionization has taken place in its volume. It kept very cold to minimize the current produced by thermal activation of electrons.
Collimator: it is used on the scintillation detector to limit its counting volume. It is a specially designed lead shield with one or more holes in
It has two types:1 – The open flat field collimator: it is useful for detecting gamma rays from a relatively large volume such as the thyroid or kidney.2- The focused collimator : it has a number of trapped holes oriented to point at a small volume 7.5 to 12.5 cm from it , it is often used in nuclear medicine

what is friction force? why does opposes the motion?
In whole analog to the work energy theorem for the translator motion, it might be stated for rotational motion as: Δ W rot = K rot The net rotational work given by the force
What is the difference between blow holes and porosity
Harmonicmotion is considered simple if it is undamped, i.e. if it keep on to oscillate uniformly over time. Of particular interest are the frequency f or also period T of the oscil

m2, 8.5 kg, is accelerating down an incline at a constant rate. m1 is being pulled by a string attached between the two masses. The coefficient of friction between m1 and the horiz
Engineers and technologist engage themselves in the design and manufacturing of machine like latches, engines, motors, generators, bulldozers etc. And in the fabrication of vehicle
At certain sharply explained wavelengths, the power of X-rays is very large as marked K alpha, K beta .... As shown in figure. These X-rays are called as property of X-rays. At oth
