Actually it is due to the nucleus's. the protons + neutrons) of the individual atoms. Each element (or isotope) have different Atomic Mass (mainly due to the nuclear mass) and different atomic number (equal to nos of protons in the nucleus). The canal rays (also known as the anode rays are actually the nucleus of the atoms that have been ripped of electrons, hence acquiring an overall positive charge equal to the number of protons in the nucleus of the atom. But since different elements have different mass numbers and atomic numbers hence the e/m ratio varies for the elements canal rays.
A cathode ray in a gas-filled tube is deflected by a magnetic field due to the Lorentz force acting on the charged particles in the ray. A wire carrying an electric current can be pulled by a magnetic field through the interaction of the magnetic field and the moving charges in the wire. A cathode ray is deflected away from a negatively charged object due to the repulsion between the negatively charged object and the negatively charged particles in the cathode ray.
The charge of the particle in cathode rays is negative. This was determined by J.J. Thomson through his experiments with cathode ray tubes in the late 19th century, which led to the discovery of the electron.
Canal rays, sometimes called anode rays, were first observed in by Eugen Goldstein in 1886. These rays are streams of positive ions in a rarefied gas and have a higher mass compared to electrons.
When cobalt-60 emits a gamma ray, it remains as cobalt-60. The emission of a gamma ray does not change the identity of the cobalt-60 isotope.
The specific code for a barium enema with or without a KUB (kidney, ureter, bladder X-ray) would depend on the specific details of the procedure. However, the most commonly assigned code for a barium enema is CPT code 74280. Additional codes may be used for the KUB X-ray if performed. It is important to consult the current version of the CPT code book for accurate and up-to-date coding information.
Anode ray is positive and cathode ray is negative
An x-ray tube where the anode is held still, rather than rotated as would happen in the rotating anode tube.
Cathode ray.
Cathode Ray
A rotating anode promotes cooling between exposures by distributing the intense beam from the cathode over the surface of the anode. A rotating anode tube lasts a lot longer than a stationary x-ray tube.
The x-ray tube target is rotated to reduce wear and tear on the anode and to keep the anode from overheating.
Anode rays differ from cathode rays in several aspects and their specific charge(charge/mass or e/m ratio) is an important feature. The reason lies in how anode rays are produced. Anode rays are produced when a gas at low pressure is subjected to a high voltage(10,000 Volts). Under these conditions, the atoms of the gas get ionized, i.e. they lose some electrons and thus become cations(positive ions). It is a stream of these positive ions that become 'anode rays'. However, the atomic masses of different gases are different and hence, the mass of anode ray particles varies when you use different gases in the discharge tube and hence, the charge/mass ratio also varies. Whereas, in the case of cathode rays, the cathode ray particles are nothing but electrons. Their charge and mass is constant no matter what gas you use in the discharge tube. So, their charge/mass ratio remains constant. (ANSWER BY RIZWAN FROM PAKISTAN)
The cathode of an electron gun.
A perforated cathode plate is used in the production of anode rays to allow some electrons to pass through and create a beam of electrons. This helps in generating a focused and directional electron beam for studying the properties of anode rays. The perforations also provide a way for the electrons to accelerate towards the anode, contributing to the formation of anode rays.
In X-ray tubes, electrons are emitted from a cathode source to a anode target through a process called thermionic emission. Electrons are then accelerated towards the anode target via a potential energy difference between the cathode and anode. The interaction between the accelerated electrons and atoms in the anode target causes the emission of X-ray. Efficiency of the X-ray tube is impaired by the kinetic energy of the accelerated electrons being loss as heat and only 1% of the remaining energy is used to emit X-ray.
when the cathode filament emits the electron and because of the high vaccum inside the tube with a high voltage who is applied on anode (the destination) the electron will accelerate to the anode and the anode will emits the x-ray photon directly after strike of the mentioned electron. the power of x-ray or peneration is determined of the anode high voltage.
There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.
