The effects of radiation depend on the type, energy, and location of the radiation source, and the length of exposure.
Which is the ability of radiation to pass through matter?
The ability of each type of radiation to pass through matter is expressed in terms of penetration power. The more material the radiation can pass through, the greater the penetration power and the more dangerous they are.
What factors effect radiation?
Radiation dose to the patient is influenced by many factors, such as the nature and complexity of the procedure, patient, prior radiation exposure, operator, and fluoroscopic equipment.
What factors affect the ability of a radioactive particle to pass through a shield?
Radiation Energy. The greater the energy of the radiation (e.g., beta particles, gamma rays, neutrons) the thicker the shield must be. 2. The shield material.
What are the three key factors for limiting exposure to radiation?
For reducing radiation exposure, there are 3 principals: time, distance, and shielding.
- Time. Radiation exposure can be accumulated over the time of exposure. …
- Distance. A greater distance from the radiation source can reduce radiation exposure. …
- Shielding.

What is radiation How does it affect an object?
The main effect radiation has on matter is its ability to ionize atoms to become ions, a phenomenon known as ionization, which is very similar to the photoelectric effect. Radioactive particles or electromagnetic waves with sufficient energy collide with electrons on the atom to knock electrons off the atom.
How does electromagnetic radiation affect matter when it is absorbed by matter?
In physics, absorption of electromagnetic radiation is how matter (typically electrons bound in atoms) takes up a photon's energy — and so transforms electromagnetic energy into internal energy of the absorber (for example, thermal energy).
What factors affect the amount of heat transferred by radiation?
The hotter the body, the more infrared radiation it radiates in a given time. The rate at which an object transfers energy by heating depends on: the surface area, volume and material of the object and the nature of the surface with which the object is in contact.
What are types of radiation?
The three most common types of radiation are alpha particles, beta particles, and gamma rays.
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.
