Nuclear weapons emit large amounts of thermal radiation as visible, infrared, and ultraviolet light, to which the atmosphere is largely transparent. This is known as “Flash”. The chief hazards are burns and eye injuries. On clear days, these injuries can occur well beyond blast ranges, depending on weapon yield. HowRead More →
Early side effects, such as nausea and fatigue, usually don’t last long. They may start during or right after treatment and last for several weeks after it ends, but then they get better. Late side effects, such as lung or heart problems, may take years to show up and areRead More →
Typically, people have treatment sessions 5 times per week, Monday through Friday. This schedule usually continues for 3 to 9 weeks, depending on your personal treatment plan. This type of radiation therapy targets only the tumor. Why can’t you have radiation therapy twice? In most cases the total dose ofRead More →
6.1 Examples of Blackbody Radiators. Remember that all objects are blackbody radiators, and that the spectrum of an object’s blackbody radiation is determined by the object’s temperature, and by its emissivity. What is black body radiation example? Blackbody radiation refers to the spectrum of light emitted by any heated object;Read More →
A pyranometer is a type of actinometer used for measuring solar irradiance on a planar surface and it is designed to measure the solar radiation flux density (W/m2) from the hemisphere above within a wavelength range 0.3 μm to 3 μm. What can be measured using a Pyrheliometer? A pyrheliometerRead More →
For effective power supply noise filtering, a design guideline is to use ferrite beads at about 20% of their rated dc current. As shown in these two examples, the inductance at 20% of the rated current drops to about 30% for the 6 A bead and to about 15% forRead More →
In home security, IR sensors are commonly used for motion detection and cameras. Since IR technology is safe, reliable, and inexpensive, devices that use IR detection are known for also being safe, reliable, and inexpensive. What is better PIR or microwave sensor? Both sensor types have their own advantages andRead More →
Some of the re-emitted energy remains within the atmosphere or returns to the surface and warms the lower atmosphere and surface. The rest of the re-emitted energy leaves the atmosphere and goes into space. … Adding more greenhouse gases decreases the amount of infrared radiation energy leaving the atmosphere. WhatRead More →
The Military Tunnel Scientist is very powerful, often wielding military grade weapons, such as a LR-300 or a MP5. They occasionally drop high grade, but rare weapons such as the M92 or SPAS-12. They are spotted around the unique Military Tunnel monument and do not roam it alone. What cardRead More →
Yes, humans give off radiation. Humans give off mostly infrared radiation, which is electromagnetic radiation with a frequency lower than visible light. This effect is not unique to humans. … The sun is hot enough that most of its thermal radiation is emitted as visible light and near infrared waves.Read More →
