The columns of white smoke seen in films of nuclear tests are smoke trails left by small rockets. These devices were used to measure the size (that is the height and diameter) of the explosion. The smoke columns provided scale and then the size of the fireball could be calculated mathematically.
What else can I help you with?
How you build a fire detecter?
Actually they are smoke detectors, they detect the result of the fire, smoke. A smoke detector works as follows: There is a chamber with a small nuclear source in it. Smoke particles are hit by the radiation and are ionized, ie, an electron is knocked off the particle leaving the particle with a charge on it. The chamber has two parallel plates in it with a voltage across the plates. The ionized particles are attracted to one of the plates, causing an electric current to flow. This current is amplified and detected and sets off the alarm.
Why do you have to test an ionizing smoke detector?
You have to test it frequently, the reason is that smoke may be visible or may be not and you want to see all particles that emanate from any kind of smoke, specially during night time when you are asleep. Most of dust/ash particles may not be visible and via ionizing detector they will be!!!! Alarm will go off making alert sound and you will be safe. So, sumirizing, you need to test ionizing smoke detector to see if sensor is in ok condition.
What does a smoke stack do on a steamship?
A smoke stack on a steamship vents exhaust from the ship's boiler to the air outside.
What happens if your smoke detectors goes off but there's no smoke?
This may because specs of dust can cause activation of the detector as it has the same effect as smoke. Spiders also can crawl into the sensors which does the same thing- same way with deodrant, paintfumes etc. It also may be because the smoke detector is just faulty.
Why the chimney of a big mill very tall?
The chimneys or smoke stacks from factories and mills were made very tall to keep the smoke from choking everyone in the nearby area. With a taller chimney the smoke would usually dissipate before it hit the ground.
Why does mushroom cloud form in after a nuclear explosion?
For the same reason they form following any explosion: heated air from explosion is lighter than surrounding air, making it buoyant and it therefor rises. The cloud is visible because of entrained debris, vaporized metal, smoke from fires, etc. produced by the explosion (nuclear or not). Nuclear mushroom clouds are simply more spectacular because more energy was released, making them hotter.
Why does the sky turn black after a nuclear explosion?
It might be because of dust in the atmosphere elevated by the explosion. Particles of dust absorb and scatter visible light very well. And the sky turn to black because there is on light coming through dust clouds.
Has there ever been a nuclear explosion?
Yes, Hiroshima, Nagasaki were both bombed with Nuclear weaponsChernobyl was a nuclear powerplant that suffered a meltdown, and a nuclear explosionAnd there were countless Nuclear testsThere was NO nuclear explosion at Chernobyl! The explosion was a steam explosion that blew the roof off the building and maybe 1/4 of the reactor contents up in the air, all immediate debris landed within a short distance of the plant. Then the graphite moderator of the reactor core caught fire carrying radioactive smoke that dropped fallout on millions of surrounding square miles. If it had had a containment building as all US nuclear power plants are required, to the steam explosion and fire would have been completely contained with no offsite contamination!The number of nuclear tests is quite countable, see: Swords of Armageddon by Chuck Hansen.
Where was the nuclear explosion at in 1986?
I don't know of one specifically, there was still underground nuclear testing at the time so there might have been several that year. If you are thinking of the reactor explosion at Chernobyl that year, that was not a nuclear explosion, just a large steam explosion when the coolant water flash vaporized blowing the roof off the reactor. Once the graphite moderator in the core was exposed to air it caught fire, this was the worst part of the disaster as burning graphite is nearly impossible to put out and the smoke was carrying all kinds of radioactive material from deep in the core.
Can smoke from a gas explosion kill a pine tree?
NO
Are the big towers in a nuclear power plant smoke stacks?
No, the big towers in a nuclear power plant are not smoke stacks. These towers are cooling towers used to dissipate excess heat generated during the nuclear power generation process, not to release smoke or emissions.
What is made during an explosion?
First you must know that fire needs fuel, oxygen, and heat. When this happens a lot of gases are released from the fuel. If this happens in a closed container the gases build up and store energy. When the container can't hold any more energy this is when an explosion occurs. Basicly an explosion is when a lot of energy is released.a explosion occurs when a time for a bomb is u or if gas or petrolatum leeks.In military explosion also occurs with the use of an EFP (explosively formed penetrator)
What are some examples of the misuse of science or technologly?
some examples are: 1: the nuclear explosion which we are misusing while in other countries people used the nuclear explosions for producing electricity 2: we are misusing the factories we r mixing the chemicals in our clean water and the factories are also producing smoke!
Is a nuclear mushroom cloud smog?
no, smog is a contraction of smoke and fog(originally observed in London when houses burned coal for heat and cooking), however it is usually used now to refer to a haze produced photochemically from car exhaust (photochemical smog). A mushroom cloud is a mixture of debris picked up, vaporized metal, smoke from fires, etc. produced by an explosion (nuclear or not).
What can happen if you smoke around an oxygen tank?
fire - explosion - boom.
Do nuclear power plants produce whit or black smoke?
black smoke.
What were the effects of the chernobyl nuclear disaster?
To put it simply radioactive fallout. You can't inhabit the area any more. There is no drinkable water left. It killed many people and many more were disfigured and have contracted cancer and other related diseases, even now Clarification, there was no nuclear explosion at Chernobyl. The explosion that blew the roof off the reactor building was a steam explosion. Also all the fallout distributed was carried by the smoke of a graphite fire, started when the steam explosion exposed the reactor's hot graphite moderator to air (sudden release of Wigner Energy in the graphite probably also helped ignite it).
