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
Will fiber optics systems be cheaper in the future? Lighting fiber optics is not a certain mass-market product and maybe will never be. Even today mainly systems are, at least
A ring forming a magnetic circuit is made from two materials; one part is mild steel of mean length 25cm and cross-sectional area 4cm 2 , and the remainder is cast iron of mea

How to find out neutral point ? What all things we require to equate or form a equation to find the neutral poind and how to do it?
An atom in a solid state has no degrees of freedom for transnational and rotational speed. At great temperatures due to vibration along 3 axes it has 3 Χ2(directions) = 6 degrees
When a P-type semiconductor is suitably joined to an N-type semiconductor, then resulting arrangement is called P-N junction or P-N junction diode Depletion region : On account
The decrease of mass is related to the binding of the individual particles together inside the nucleus. Therefore every stable nucleus has a mass which is less than the total ma
So I have a question here and I am totally lost: A car starts from rest and accelerates at a constant rate of 1.1 m/s2. If the radius of the car wheels is 29.0 cm, and the final an
1. Cell growth. if V is the volume of a spherical cell, then, in certain cell growth or for some fetal growth models, the rate of change of V is given by dV/dt =kV2/3, where k
