Radiation can damage electronic hardware in environments such as nuclear power plants and space exploration. Radiation hardening involves creating physical and logical shields to protect the hardware, but the process is intense and time-consuming. Testing is done in radiation chambers, but results may differ from real-life conditions. In radioactive environments, such as those experienced with […]
To protect against cell phone radiation, limit use, choose a phone with a low specific absorption rate (SAR), avoid holding it close to the head, and use speakerphone or text messaging. Products like shields, air tube headphones, and those using MRET or SRT technology claim to provide further protection. There are several safety measures that […]
Low-dose mammography radiation can be harmful to young women with a genetic predisposition to breast cancer, who should use alternative detection methods. Repeated x-rays can also cause cancer and heart disease. Mammography radiation can cause irreversible damage to specific DNA cells, increasing the risk of breast cancer. Experts recommend discussing recent radiation exposure with a […]
Radiation shielding uses materials to protect against ionizing radiation, which can cause cancer and mutations. There are two types of radiation: ionizing and non-ionizing. Shielding materials include lead glass, lead aprons, and packed dirt. It is best to limit exposure and work at a safe distance from radiation sources. Radiation shielding is the use of […]
Radiation exposure can occur through occupation, medical treatment, or emergency situations. It’s important to remain calm and seek medical help in emergencies. There is a distinction between exposure and contamination, and different types of contamination require different responses. The best way to deal with radiation exposure in an emergency is to get away from the […]
UV radiation from the sun can cause skin damage, including sunburn and skin cancer. It can also contribute to skin aging, eye damage, and cataracts. The UV Index rates the strength of UV rays and people can protect themselves by avoiding sun exposure during peak hours, wearing sunscreen, sunglasses, and hats. Ultraviolet (UV) radiation is […]
Airline crew members are exposed to high levels of cosmic ionizing radiation, which can cause health problems such as cancer and reproductive issues. They also face exposure to UV radiation, gamma-ray and X-ray radiation, chemical flame retardants, and engine leaks. The Harvard Flight Attendant Study found that cabin crew have higher rates of many types […]
Becoming a radiation therapist involves completing an accredited program, which can vary in length and prerequisites, and passing a competency exam. A willingness to help others, attention to detail, and aptitude in math and science are important qualities. Certification from the American Registry of Radiologic Technologists is often required. In Canada and the UK, programs […]
Medical radiation physicists research and implement radioactive materials to treat illnesses such as cancer, while ensuring safe use and maintenance of devices. They experiment with different proportions of radiation and optimize treatment while considering patient comfort. They also work with X-ray technicians and update safety parameters for personnel to avoid radiation poisoning. A medical radiation […]
Radiation oncology jobs involve treating cancer with radiotherapy. Physicians, physicists, and therapists are needed. Radiation oncologists prescribe treatment, physicists design and engineer treatment systems, dosimetrists calculate radiotherapy doses, and radiation therapists administer treatment. Medical physicists can also design new medical equipment. Dosimetrists work closely with physicians and radiation oncologists to provide the proper dosage of […]
A radiation pyrometer estimates thermal radiation without direct interaction with a surface, by detecting red energy spectrum. It needs regular cleaning to ensure accurate results. It is commonly used in metallurgy and smelting industries. A radiation pyrometer is a device that uses optical technology to estimate the thermal radiation of a surface, without the user […]
Solar radiation is the spectrum of light emitted by the sun due to nuclear fusion in its core. It is studied for its effects on Earth’s weather and astronomy. Only a small fraction of solar radiation reaches Earth, but it is still much greater than energy consumed on Earth. Solar radiation is measured in watts […]
UV radiation is a range of light beyond human perception that can cause sunburn and skin cancer. However, it also has health benefits such as inducing vitamin D production. UV technology is widely used, and it can be produced artificially. Sunscreen can prevent sunburn, and excessive exposure should be avoided. Ultraviolet (UV) radiation is a […]
Ionizing radiation is emitted by unstable chemical elements and can be harmful to human health. Alpha particles, beta particles, and gamma rays have different effects. Non-ionizing radiation, such as visible light and microwaves, is safer. Alpha particles are large and cannot penetrate skin, but can cause cancer if ingested. Beta particles can travel farther and […]
Non-ionizing radiation, such as radio waves, infrared, microwaves, visible light, and near ultraviolet, does not have enough energy to ionize molecules or atoms. While less harmful than ionizing radiation, it can still cause harm to living organisms. Laser light is the only potentially harmful form of non-ionizing radiation, and following safety procedures can protect against […]
Ionizing radiation, from sources like cosmic rays and nuclear decay, can cause damage to the body’s cells and DNA, leading to cancer or death. Protective measures are in place in industries like nuclear power plants and hospitals to prevent exposure. There are many effects of ionizing radiation depending on the dose you receive. Ionizing radiation […]
Electromagnetic radiation is energy-carrying particles from a source, measured by the electromagnetic spectrum. It can be beneficial, harmless or dangerous. Natural sources include the sun, while man-made sources include x-rays, radio waves and microwaves. Scientists divide it into non-ionizing and ionizing types, with the latter being used in cancer treatments. Overexposure can cause illness and […]
Infrared radiation is a type of radiation in the electromagnetic spectrum, with a wavelength slightly longer than red rays. It is heat that humans can feel but not see. Infrared cameras can detect it and are used for military, astronomical, and meteorological purposes. Infrared radiation, also known as “IR,” is just one type of radiation […]
Earth’s radiation is the energy emitted back into space, largely as a percentage of the total radiation received from the Sun. Albedo, or the amount of light energy reflected by a stellar body, is expressed as a ratio or percentage. The net loss of energy from Earth’s surface is minimal due to atmospheric damping effects. […]
Neutron radiation, composed of neutral subatomic particles found in nuclear reactors and bombs, is a health risk and the fourth major type of radiation. Discovered in the 1930s, it played a crucial role in the first nuclear reactor and bomb. Neutron radiation tends to be absorbed by nuclei, making it radioactive and dangerous to humans. […]
