What are the products of radioactive decay?
The radioactive decay products we will discuss here are alpha, beta, and gamma, ordered by their ability to penetrate matter.
Alpha denotes the largest particle, and it penetrates the least.
Alpha particles carry a positive charge, beta particles carry a negative charge, and gamma rays are neutral..
What are the 3 types of radioactivity?
The three most common types of radiation are alpha particles, beta particles, and gamma rays.
What do all types of radioactivity produce?
Radioactive elements emit ionizing radiation as their atoms undergo radioactive decay. gamma raysA form of ionizing radiation that is made up of weightless packets of energy called photons. Gamma rays can pass completely through the human body; as they pass through, they can cause damage to tissue and DNA..
Who invented radioactivity?
Henri BecquerelIn one of the most well-known accidental discoveries in the history of physics, on an overcast day in March 1896, French physicist Henri Becquerel opened a drawer and discovered spontaneous radioactivity.
What are the 5 types of radioactive decay?
There are 5 different types of radioactive decay.Alpha decay follows the form: … Beta negative decay follows the form: … Gamma decay follows the form: … Positron emission (also called Beta positive decay) follows the form: … Electron capture follows the form:
How much radiation is in a banana?
The radiation exposure from consuming a banana is approximately 1% of the average daily exposure to radiation, which is 100 banana equivalent doses (BED). The maximum permitted radiation leakage for a nuclear power plant is equivalent to 2,500 BED (250 μSv) per year, while a chest CT scan delivers 70,000 BED (7 mSv).
How can you protect yourself from radiation?
Staying inside will reduce your exposure to radiation.Close windows and doors.Take a shower or wipe exposed parts of your body with a damp cloth.Drink bottled water and eat food in sealed containers.
What are the 7 types of radiation?
This range is known as the electromagnetic spectrum. The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
What are 4 types of radiation from the sun?
Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
What are the things that have radiation?
The 7 Most Radioactive Items in Your HomeBrazil nuts. Brazil nuts (especially the ones grown in Brazil) grow on trees with deep roots, which reach down to soil high in natural radium, a source of radiation. … Bananas. … Your body. … Smoke detectors. … Granite countertops. … Your grandma’s dinnerware. … Cigarettes.
Which radiation is the most dangerous?
alpha radiationalpha radiation is the most dangerous because it is easily absorbed by cells. beta and gamma radiation are not as dangerous because they are less likely to be absorbed by a cell and will usually just pass right through it.
What is radioactivity in simple words?
1 : the giving off of rays of energy or particles by the breaking apart of atoms of certain elements (as uranium) 2 : the rays or particles that are given off when atoms break apart. radioactivity. noun.
What are 4 uses of radiation?
Today, to benefit humankind, radiation is used in medicine, academics, and industry, as well as for generating electricity. In addition, radiation has useful applications in such areas as agriculture, archaeology (carbon dating), space exploration, law enforcement, geology (including mining), and many others.
What are the 4 types of radiation?
There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. The first is an alpha particle.
Which type of radiation has a +2 charge?
alpha particleAn alpha particle is identical to a helium atom that has been stripped of its two electrons; thus, an alpha particle contains two protons and two neutrons. Because an alpha particle has no electrons to balance the positive charge of the two protons, it has a charge of +2 and can be represented as He2+.
