Laser
Dark matt surfaces absorb heat radiation falling on them much better than bright glossy surfaces, such as gloss white or silver. They also emit much more heat radiation (at any given temp.)
Your best option is to seek out information about "Acute Radiation Sickness". This should help you understand this better.
Yes, enough of it can. But boron or cadmium would be better.
When you burn your finger, it most often happens when you touch somethinghot, and the heat transfers to the skin by conduction.A much better example of burning yourself by radiation is sunburn.
Three and Four Level Laser SchemesWe have said that the two level scheme is not generally feasible for laser action. There are two main reasons for this. The first reason is that the energy being used to pump the particles into the upper laser state has an equal probability of stimulating them back down. Thus it is not possible to get nore than half of the particles into the excited state. The three level scheme gets around this problem by first exciting the particles to an excited state higher in energy than the upper laser state.(See figure below) The particles then quickly decay down into the upper laser state. It is important for the pumped state to have a short lifetime for spontaneous emission compared to the upper laser state. The upper laser state should have as long a lifetime (for spontaneous emission) as possible, so that the particles live long enough to be stimulated and thus contribute to the gain.The four level laser scheme goes one step further and also depopulates the lower laser level by a fast decay process.(see figure below) This greatly decreases the loss of laser photons (v2) by stimulated absorption processes since the particles in the lower laser level have a short life-time for spontaneous emission.
Well, Light Amplification by Simulated Emission of Radiation (LASER), which is artificially made, is like a million times brighter that sunlight. And that's all I know. Find out more in Wikipedia yourself. (P.S. No offense for that sentence.)
for better amplification ...by instrumentation amplification we get the output admittance will be more
wet dream
Yes, about 6 times better, but they aren't the champs of radiation resistance.
No. An acronym is a word where the letters stand for something like SCUBA (Self-Contained Underwater Breathing Apparatus) or NASA (National Air and Space Administration). A visual aid is a picture, display, PowerPoint, etc. that better illustrates the main idea of a presentation or invention. "Acronym" means a word formed out of the first letters of several other words. "Federal Bureau of Investigation" becomes "FBI". "FBI" is an acronym. "Mothers Against Drunk Driving" becomes "MADD". "MADD" is an acronym. "Light Amplification (by) Simulated Emission (of) Radiation" becomes "LASER".
Population growth. When the economy began to do better, people were better off and could live much longer lives.

The EPA historically has not had enough power to enforce better emission regulations. Most of the emissions in the US, almost 50%, come from coal-burning power plants.
Neither is better. They are used for different purposes. Geiger counters detect rates of beta and gamma radiation, emitting clicks as they are detected. Some types can detect alpha particles also. They are used as devices in the field, to determine such things as safety of an object or place. Bubble chambers also detect ionizing radiation, but they do so by recording, rather than rates of emission. They have historically been used for research, though they are used less now than they have been in the past.
If you are interested in taking a couple courses on radiation therapy, then there are many different kinds of schools that offer different courses in radiation therapy.
Plants will grow better in a garden. Car emission fumes are harmful to plants.
No, Green house effect is the phenomenon when the green house gas would trap solar radiation. Mostly it could trap (absorb) radiation on infrared region better than visible range and so it result to higher temperature of this planet. The Global warming is the theory that earth temperature is increasing due to man made emission of CO2 through process of Green house effect.
