After the Chernobyl disaster, an increase in thyroid nodules elevated anti-TPO and anti-Tg antibodies. More underactive thyroid cases were reported in people living in the most affected areas of Ukraine, Belarus, and Russia (9). What health problems did Chernobyl Cause? Among the 600 workers onsite, increased incidences of leukemia andRead More →
The carcinogenic effect of MW irradiation is typically manifested after long term (up to 10 years and more) exposure. Is it bad to stand in front of the microwave? Yes, you can stand a safe distance in front of the microwave. Microwave ovens are designed to keep in radiation. …Read More →
Radiation therapy to try and cure cancer is usually delivered daily, Monday through Friday, for about five to eight weeks. Weekend breaks allow normal cells to recover. Shorter durations of radiation therapy may be used to relieve symptoms. Is radiation localized or systemic? Radiotherapy is generally used to treat aRead More →
One of Stephen Hawking’s famous theorems has been proven after researchers observed ripples created in space-time by the fusion of two black holes. The theorem was first proposed in the year 1971 that claimed that it was impossible for a black hole to decrease in size over time. What wasRead More →
1911 Prize: After Marie and Pierre Curie first discovered the radioactive elements polonium and radium, Marie continued to investigate their properties. In 1910 she successfully produced radium as a pure metal, which proved the new element’s existence beyond a doubt. How was Marie Curie involved in radiation? Marie Curie wasRead More →
Cerenkov radiation occurs when charged particles like electrons are moving faster than the speed of light in a particular medium. … As these charged particles move through a medium, the electric field moves with them. Is Cherenkov radiation harmful? Is the Cherenkov Radiation Dangerous? … Yes, Cherenkov radiation, rather particlesRead More →
Due to the finite size of the focal spot, when the object is further away from the detector, the edges in the image of the object get blurred (Penumbra). The total blur (degradation) in the final image is a combination of detector and focal spot blurring. What are the effectsRead More →
Absorption of a dose between 0.5 and 2 sieverts (Sv) will result in a light reaction involving nausea, asthenia and vomiting between 3 and 6 hours after the exposure. Somewhere between 4 and 4.5 Sv lies the so-called DL50 level, which is the point at which exposure will be fatalRead More →
The Earth radiates energy at wavelengths much longer than the Sun because it is colder. Part of this longwave radiation is absorbed by greenhouse gases which then radiate energy into all directions, including downwards and thereby trapping heat in the atmosphere. What happens to solar radiation when it enters Earth’sRead More →
Astronauts face a constant specter of radiation, as particles streaming off the sun and high-energy cosmic rays constantly bombard their bodies. Left unchecked, radiation can trigger all sorts of health issues, most notably boosting an astronaut’s danger of developing cancer. What happens if an astronaut is exposed to radiation? RadiationRead More →
