Rad
Gamma radiation. Alpha radiation is the least penetrating, beta radiation penetrates and lasts longer than alpha but also "dies out" relatively quickly, but Gamma radiation will not only penetrate deep, but it will also stay long.
rem is an acronym for roentgen equivalent man, the unit used to measure the amount of radiation that results in the same amount of human tissue damage as that caused by one roentgen of X-rays.
A unit of absorbed energy from ionising radiation equal to one thousand grays. A gray (Gy) is the SI unit of absorbed radiation dose of ionising radiation, defined as the absorption of one joule of ionising radiation by one kilogram of matter (usually human tissue).
Pathogens such as bacteria, viruses, and fungi can directly attack human tissue by invading and replicating within the cells or tissues of the body. This invasion can lead to damage of the host tissue, triggering an immune response and causing symptoms of infection.
One example of a small organism that can damage and destroy tissue in animals, humans, and plants is a bacterium called Pseudomonas aeruginosa. This bacterium is known to cause infections in a variety of hosts, leading to tissue damage and destruction if left untreated.
Nuclear radiation can damage human tissue by causing DNA mutations, cell death, and inflammation. This can lead to health problems such as cancer, radiation sickness, and long-term tissue damage. The severity of the effects depends on the dose, duration of exposure, and type of radiation.
Radiation exposure occurs from medical equipment, ultraviolet radiation from the sun and small but steady radiation from cell phones, microwaves and electrical towers. It damages human tissue by leaving the cells unstable, which can lead to cancer.
Ionizing radiation, such as gamma rays, X-rays, and certain particles like alpha and beta particles, can cause damage to human tissue by breaking chemical bonds in cells. This can lead to DNA damage, cell death, and potentially increase the risk of developing cancer or other health problems.
As a general rule, tissue that has a higher metabolic rate is more susceptible to radiation damage. Hair follicles, blood and blood forming tissue (marrow), and tissue along the intestinal tract are examples.
infrared radiation is invisible to humans
Gamma radiation. Alpha radiation is the least penetrating, beta radiation penetrates and lasts longer than alpha but also "dies out" relatively quickly, but Gamma radiation will not only penetrate deep, but it will also stay long.
Ionizing radiation, such as X-rays and gamma rays, have enough energy to remove tightly bound electrons from atoms, leading to cellular damage and potential harm to living human tissue. Exposure to high levels of ionizing radiation has been linked to an increased risk of cancer and other health issues.
Radiation requires a source that emits energy in the form of electromagnetic waves or particles. This energy can then interact with matter, such as human tissue, causing ionization or other effects. Protection measures, such as shielding or distance, are also important when dealing with radiation to minimize exposure risks.
The unit of radiation is the Gray (Gy), which measures the absorbed dose of ionizing radiation in tissue. Another common unit is the Sievert (Sv), which adjusts the absorbed dose to account for different types of ionizing radiation's varying biological effects on human health.
Beta radiation can penetrate human tissues to a depth of a few millimeters to a few centimeters, depending on the energy of the beta particles. Higher energy beta particles can penetrate deeper into tissues, potentially causing damage to cells and DNA along their path.
Gamma radiation is considered the most dangerous type of radiation due to its high energy and ability to penetrate deep into tissues, causing damage at the cellular level. Exposure to high levels of gamma radiation can lead to severe health effects, including radiation sickness, DNA damage, and an increased risk of cancer.
The good about radiation is it can stop the abnormally growing cells in cancer,and radiation will let us visuallized the entire human body. Disadvantage with radiation when in great amount can cause sterility.
