What does the amount of radiation depend on?

The amount of radiation mainly depends upon the nature of body, temperature of the body and type of surface of the body.

What is radiation measured in chemistry?

The SI unit for measuring radiation dose is the gray (Gy), with 1 Gy = 1 J of energy absorbed per kilogram of tissue. In medical applications, the radiation absorbed dose (rad) is more often used (1 rad = 0.01 Gy; 1 rad results in the absorption of 0.01 J/kg of tissue).

On which of the following factors does the amount of radiation mainly depends?

Solution(By Examveda Team) Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object It depends on nature of the body, its temperature and kind & extent of its surface.

At what factors heat absorbed on radiation by the body depends on?

More the heat capacity of a body, more will it absorb heat energy. Color of the body. Dark colors absorb more heat, black surface does the most, while the white surfaces do the least. Temperature of the body.

What are the units of radiation measurement?

The units of measurement for radioactivity are the becquerel (Bq, international unit) and the curie (Ci, U.S. unit). Exposure describes the amount of radiation traveling through the air.

What is the unit in which radioactivity is measured Mcq?

Radioactivity or the strength of radioactive source is measured in units of becquerel (Bq). 1 Bq = 1 event of radiation emission or disintegration per second.

Why are there so many units for radiation?

Because some people are afraid to switch to the metric system. As with distance, weight, and temperature, doses of radiation can be expressed in either SI units (sieverts) or U.S. customary units (rem).

On which of the following factors does the emissive power of a body depend?

The emissive power of a body depends on its temperature and nature of its surface.

Which one has the highest value of overall heat transfer coefficient?

Which one is having highest value of overall heat transfer coefficient? Explanation: Overall heat transfer coefficient for air condensers is 780 W/m2 K while that of steam, alcohol condensers and air to various gases are 340 W/m2 K, 700 W/m2 K and 550 W/m2 K. 7.

What are the factors on which heat depends on?

Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance.

What unit is used to measure radiation?

Absorbed dose is the amount of radiation absorbed by an object (or person). This is the amount of exposure that actually “sticks” in the material. The units used to measure absorbed dose are the rad ( r adiation a bsorbed d ose) and the gray (Gy). The rad is the CGS unit of absorbed dose and the gray is the SI unit.

Will 150 rads of radiation kill a person?

Even there, 150 rads should not be enough radiation to kill someone, at least not immediately. However, the person would likely begin to suffer side effects, such as nausea. Some people exposed to this amount of radiation would die later on, while others would recover.

What is the lethal amount of radiation?

According to the United States Nuclear Regulatory Commission, the lethal dose of radiation is in the range of 400 to 450 rem. This level of radiation causes death to around 50 percent of a population that has been exposed over a period of 30 days.

What device measures radiation?

A radiation dosimeter is a device that measures exposure to ionizing radiation. It has two main uses: for human radiation protection and for measurement of dose in both medical and industrial processes.
