Radiation threshold is the minimum level of radiation exposure that can cause detectable effects in an organism. It is the point at which the effects of radiation, such as DNA damage or cellular harm, start to become noticeable. Exceeding the radiation threshold can lead to increased risks of health issues such as cancer and genetic mutations.

What is threshold wavelength?
Threshold wavelength refers to the minimum wavelength of light required to start a specific phenomenon, such as photoelectric effect or emission of electrons from a metal surface. Below this threshold wavelength, the desired effect does not occur.
Why for a particular metal electrons are emitted only when the frequency of the incident radiation is greater than a certain value?
Electrons are emitted from a metal surface when the energy of the incident photons is great enough to overcome the work function of the metal. This minimum energy required is equivalent to a certain threshold frequency, known as the threshold frequency. Electrons can only be emitted when the frequency of the incident radiation is greater than this threshold frequency because lower frequency photons do not possess enough energy to overcome the work function and release electrons from the metal surface.
What is the maximum amount of radiation a human body can tolerate?
100 milliSieverts is the smallest radiation dose clearly linked to cancer. 1 Sievert is the smallest radiation dose required to induce radiation sickness. The average person absorbs 250 millirems over a lifetime.
What is the difference between absolute threshold and difference threshold?
absolute threshold is the lowest level that a person will feel sensation differential threshold is the minimal difference that a person can detect between two similar stimuli For example a change in volume in certain frequencies would be crossing the absolute threshold, how much that change would need to be for someone to detect it would be dealing with the difference threshold.
What is the difference between threshold of hearing and absolute threshold of hearing?
The absolute threshold of hearing is the lowest possible tone/decibel you could possibly hear. (This differs form person to person). The Differential Threshold is the point at which a person recognizes the decibel level has changed.Hope this answers your question, just learned this in psychology!
What kind of does response curve indicates there is no safe does of radiation?
non-threshold
When electromagnetic radiation above the threshold frequency falls on an object it emits electrons?
Hhn
Please suggest a good topic for research for medical technology students?
Threshold radiation dose.Some recent studies have indicated that there may be a threshold dose of radiation that can be administered to a patient that will not increase their likelihood of developing cancer. Though it has not been proven it may also be that administering a dose below this threshold some time before the patient undergoes radiation therapy may "warn" healthy cells around the cancerous area and could potentially increase their survival and recovery rate.
What is threshold wavelength?
Threshold wavelength refers to the minimum wavelength of light required to start a specific phenomenon, such as photoelectric effect or emission of electrons from a metal surface. Below this threshold wavelength, the desired effect does not occur.
What is the threshold frequency of cesium?
The threshold frequency of cesium is approximately 3.3 x 10^14 Hz. This is the minimum frequency of electromagnetic radiation required to eject electrons from the surface of cesium via the photoelectric effect.
How can one determine the threshold frequency for a given material or experiment?
The threshold frequency for a material or experiment can be determined by conducting a series of experiments with different frequencies of light or radiation. By gradually increasing the frequency until the material starts to emit electrons, the threshold frequency can be identified as the minimum frequency required for this emission to occur.
When was From Threshold to Threshold created?
From Threshold to Threshold was created in 1955.

Electrons can only be emitted when the frequency of the incident radiation is greater than this threshold frequency because lower frequency photons do not possess enough energy to overcome the work function and release electrons from the metal surface.
What is a antonym of threshold?
anti-threshold
What rhymes with threshold?
There are no perfect rhymes for threshold.
Threshold of human in db?
The threshold of hearing is 0 dB. The threshold of pain = 137.5 dB.
What is the maximum amount of radiation a human body can tolerate?
100 milliSieverts is the smallest radiation dose clearly linked to cancer. 1 Sievert is the smallest radiation dose required to induce radiation sickness. The average person absorbs 250 millirems over a lifetime.
