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
Evaluate the speed of the block A 2.00-kg block is attached to a spring force constant 500N/n. The block is pulled 5.00 cm to the right of the equilibrium and released from rest
State Huygens ' Principle. For reflection of a plane wave front at a plane reflecting surface, construct the corresponding reflected wave front. Using this diagram, state that angl
The effects of open circuits: An open circuit is essentially a break in the circuit. An open circuit in a series circuit will prevent the flow of current through the circuit. W
Number of electrons in the outermost orbit of the element of atomic number 15 is: (1) 1 (2) 3 (3) 5 (4) 7 Ans: 5
What are the components of endoscope? An endoscope can consist of following components • A rigid or flexible tube • A light delivery system to clarify the organ or object
If small test charge is taken as positive than why measured value of electric intensity be somewhat less than the actual value of elctric intensity and vica versa
Two similar simple pendulums each of length ‘l' and mass ‘m' are coupled by a spring of force constant ‘k'. Write down the expression for the normal mode frequencies of the coupled
describe the principle, construction and working of Michelson Interferometer.
