What are AphaGamma Beta rays?
Alpha, Beta, and Gamma rays are all types of radiating created and used in the splitting of an atom.
Technetium-99m emits only gamma radiation why would this type of radiation be used in diagnostic imaging rather than an isotope that also emits beta or alpha radiation?
Because alpha and beta aren't strong enough to penetrate the skin or something
What are three kinds of radioactivity?
The three major types of radioactivity are: # Alpha Radiation Alpha radiation consists of a stream of positively charged particles, called alpha particles, which have an atomic mass of 4 and a charge of +2 (a helium nucleus). When an alpha particle is ejected from a nucleus, the mass number of the nucleus decreases by four units and the atomic number decreases by two units. For example: 23892U -> 42He + 23490Th The helium nucleus is the alpha particle. # Beta Radiation Beta radiation is a stream of electrons, called beta particles. When a beta particle is ejected, a neutron in the nucleus is converted to a proton, so the mass number of the nucleus is unchanged, but the atomic number increases by one unit. For example: 23490 -> 0-1e + 23491Pa The electron is the beta particle. # Gamma Radiation Gamma rays are high-energy photons with a very short wavelength (0.0005 to 0.1 nm). The emission of gamma radiation results from an energy change within the atomic nucleus. Gamma emission changes neither the atomic number nor the atomic mass. Alpha and beta emission are often accompanied by gamma emission, as an excited nucleus drops to a lower and more stable energy state. Alpha, beta, and gamma radiation also accompany induced radioactivity. Radioactive isotopes are prepared in the lab using bombardment reactions to convert a stable nucleus into one which is radioactive. Positron (particle with the same mass as an electron, but a charge of +1 instead of -1) emission isn't observed in natural radioactivity, but it is a common mode of decay in induced radioactivity. Bombardment reactions can be used to produce very heavy elements, including many which don't occur in nature.Submitted by kuasimodo
Which notation is used to represent a beta particle?
The notations used to represent an alpha particle are either "a," "α^2+," or "He^2+." Alpha particles only have two protons and two neurons, making them essentially the same as helium nuclei, hence "He^2+."
Can beta rays pass through 1cm thick aluminium foil?
No, it cannot. Alpha particles can be stopped using aluminum foil. Beta particles (electrons) posses higher kinetic energy and have smaller cross section. Lead is widely used to stop beta particles as well as gamma particles. Gamma particles are basically high energy photons which are extremely dangerous for alive creatures. Extra precaution must be taken when you are working with such radiation.
Is losartan an alpha blocker?
Yes. Drugs ending in pril are alpha-blockers. Drugs ending in olol are beta-blockers.
Why propranolol is not used in treatment of pheochromocytoma?
Propanolol is a non-selective beta 1 and beta 2 receptor antagonist. When it is used in the treatment of pheochromocytoma, there is continued activation of the alpha 1 receptors leading to a paradoxical rise in hypertension due to the loss of vasodilatory affects inherent in beta 2 adrenergic stimulation. Case reports and reviews also show an increased incidence of pulmonary edema resultant from use of Propanolol in pheochromocytoma
What sports are beta blockers used in?
athletics
Marfan syndrome may be given what commonly used beta-blockers?
The most commonly used beta-blockers in Marfan patients are propranolol (Inderal) and atenolol (Tenormin). Patients who are allergic to beta-blockers may be given a calcium blocker such as verapamil.
Why beta blockers should be avoided in cocaine?
Beta blockers must not be used in the treatment of cocaine, amphetamine, or other alpha adrenergic stimulant overdose. The blockade of only beta receptors increases hypertension, reduces coronary blood flow, left ventricular function, and cardiac output and tissue perfusion by means of leaving the alpha adrenergic system stimulation unopposed. The appropriate antihypertensive drugs to administer during hypertensive crisis resulting from stimulant abuse are vasodilators like nitroglycerin, diuretics like furosemide and alpha blockers like phentolamine.beta-blocker
How are beta-adrenoceptor blockers used to treat heart failure?
Beta blockers can decrease the myocardial contractility and make heart failure worse. However, beta-blockers were shown to reduce mortality and morbidity in heart failure patients. This may be due to how they can block the damaging effects of sympathetic activity which is too active. Usually, beta-1 selective blockers such as carvedilol are used. Beta blockers should be used in all patients with stable heart failure with reduced LVEF. They should be used after ACE inhibitors.
What eye drop forms of beta blockers for glaucoma may not be effective when taking calcium channel blockers?
Eye drop forms of beta blockers, such as timolol (Timoptic), used to treat glaucoma.
How do beta blockers help thyrotoxic myopathy?
Beta-blockers are used to block the effects of adrenaline on peripheral tissues, as adrenergic systems are unregulated in hyperthyroidism. This affords symptomatic but temporary relief.
What is the treatment for beta blockers?
The main use of beta blockers is to treat high blood pressure.also are used to relieve.angina.prevent heart attacks.migraine, tremors, and irregular heartbeat. In eye drop form, they are used to treat certain kinds of glaucoma.
What drugs may be used to treat very severe or frequent migraines?
antiseizure medicines, antidepressants, calcium channel blockers and beta blockers
What beta blockers to treat angina and high blood pressure may not be effective when taking calcium channel blockers?
Beta-blockers, such as atenolol (Tenormin), propranolol (Inderal), and metoprolol (Lopressor), used to treat high blood pressure, angina, and other conditions.
How does the beta blocker medicines affect arthritis?
They don't.Beta blockers are used for treating:abnormal heart rhythm,high blood pressure,heart failure,angina (chest pain),tremor,pheochromocytoma, andprevention of migraines.They also have been found to prevent further heart attacks and death after a heart attack. Other uses include the treatment of hyperthyroidism, akathisia (restlessness or inability to sit still), and anxiety. Some beta blockers reduce the production of aqueous humor in the eye and therefore are used for reducing pressure in the eye caused by glaucoma.
