Alpha, from outside the body, because alpha is stopped by the skin, a sheet of paper, or a few inches of air. From inside the body, however, alpha is one of the most dangerous forms of radiation.

What is the order of the spectrum from most damiging to the least damaging?

The spectrum of electromagnetic radiation from most damaging to least damaging generally includes gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, microwaves, and radio waves. This order is based on the energy levels and potential for causing biological damage.


Which type of nuclear radiation is the least ionising?

Alpha radiation is the least ionizing type of nuclear radiation. It consists of positively charged alpha particles, which have low penetrating power and are easily stopped by a sheet of paper or clothing.


What type of radiation has the least ability to penetrate matter?

Alpha radiation has the least ability to penetrate matter. It consists of particles that are relatively large and heavy, which makes them easier to block. They can be stopped by a piece of paper or human skin.


What type of radiation is least penetrating?

Alpha radiation is the least penetrating type of radiation. It consists of helium nuclei and has low penetration power, being stopped by skin or even a sheet of paper.


What type of radiation causes most ionisation?

The electromagnetic radiation most capable of ionizing is the radiation with the highest energy per quantum. That in turn implies the radiation with the highest frequency (shortest wavelength). The highest-energy end of the electromagnetic spectrum is the region we call "gamma rays". We can't generate these, and the gamma rays we observe all originate in radioactive nuclear processes.

How much concrete is needed to block nuclear radiation?

My Astronomy professor says that we need at least 15 feet of concrete to block nuclear radiation.


What kind of radiation is least harmful to humans?

External to the body, alpha is not dangerous because it is easily stopped by the skin, but it becomes dangerous if ingested because it can then access internal sensitive organs directly. For electromagnetic radiation, visible light and infra-red are the least damaging. Ultra-violet causes sunburn)


What lists ranks nuclear radiation from most massive to least massive?

The ranks for nuclear radiation from most massive to least massive are: alpha particles, beta particles, gamma rays, and neutron radiation. Alpha particles are the most massive and have the least penetration power, while neutron radiation is the least massive and can penetrate deeply into materials.


What are the three kinds of nuclear radiation?

The three types of nuclear radiation are alpha particles, beta particles, and gamma rays. Alpha particles are helium nuclei consisting of two protons and two neutrons, beta particles are high-speed electrons or positrons, and gamma rays are electromagnetic radiation of high energy.

Experts anticipate that a incidents is the least likely to occur but would have a great impact upon the environment and people?

A nuclear incident would have a great impact on the environment and people, but would be the least likely to occur.Several people answered "biological", but I would question the "least likely" aspect. A nuclear incident would have a greater effect on the environment compared to a biological incident.
