What is the difference between X-rays and gamma rays quizlet?
– x-rays produced by interactions OUTSIDE the nucleus within an X-ray tube. – gamma rays are emitted by an unstable nucleus during radioactive decay. 1. penetration- x-rays have ability to penetrate through matter but not all penetrated equally.
What are the similarities and differences between gamma rays and X-rays?
Two of the most common forms of ionizing radiation are gamma rays and X-rays. Both forms of ionizing radiation are almost identical with exception to their source of origination. Gamma rays originate from the nucleus while X-rays originate in the electron fields surrounding the nucleus or are machine produced.
Why are X-rays used instead of gamma rays?
Changes in atoms and their nuclei can cause electromagnetic waves to be generated or absorbed. Gamma rays are produced by changes in the nucleus of an atom. They are a form of nuclear radiation. X-rays are absorbed by dense structures like bones, which is why X-ray photos are used to help identify broken bones.
Which type of radiation is the most harmful to the human body quizlet?
Radioactive materials that emit alpha and beta particles are most harmful when swallowed, inhaled, absorbed, or injected. Gamma rays are the most harmful external hazard. Beta particles can partially penetrate skin, causing “beta burns”. Alpha particles cannot penetrate intact skin.
Which electromagnetic wave type has the smallest wavelength?
gamma rays
Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
Which type of radiation is the most harmful to the human body?
Gamma rays
Gamma rays are the most harmful external hazard. Beta particles can partially penetrate skin, causing “beta burns”.
Which is the most energetic type of radiation?
Gamma rays are the most energetic form of electromagnetic radiation. They come from high-energy phenomena in space, including neutron stars and pulsars, supernovae and the regions around black holes. Sending a gamma-ray observatory into space could help solve fundamental problems in astrophysics.
Can animals see electromagnetic waves?
You might be surprised to learn that many animals are actually able to see into the UV part of the EM spectrum. From insects to fish and even certain species of mammal, this trait is quite common.
What is the highest energy?
Gamma rays have the highest energies and shortest wavelengths on the electromagnetic spectrum.
Are gamma rays safe?
The extremely high energy of gamma rays allows them to penetrate just about anything. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer. Ironically, the deadly effects of gamma rays can be used to treat cancer.
Does sun produce gamma rays?
Our Sun emits light at progressively shorter wavelengths, too: the ultraviolet, X-ray, and even gamma-ray parts of the spectrum. So, the only gamma rays from the Sun we receive here on Earth are from extreme solar events, such as the most powerful solar flares.
How dangerous is 100 micro Roentgen/hour?
A dose rate of 100 microR/hr (1 microGy/hr) is not dangerous. If this dose rate is accurate, living in it continuously (8760 hours per year) will give you a radiation dose of about 0.9 R/hr (9 mGy/yr). This is not a trivial dose – it’s about three times as much as what we’re normally exposed to in a year from natural sources (on average).
What are the dangers of X rays?
The Potential for False Positives and “Overtreatment”
Why are gamma rays dangerous?
Gamma rays are dangerous because they have a high energy to break bonds. Even in low doses they can alter the DNA in the cell and result in changed metabolic functions of the cell.
What are some negative effects of gamma rays?
