It depends on whether your exposure to radiation is internal or external. Alpha particles are the most harmful internal hazard as compared with gamma rays and beta particles. Radioactive materials that emit alpha and beta particles are most harmful when swallowed, inhaled, absorbed, or injected.It depends on whether your exposure to radiation is internal or external.

What are the different kinds of radiation effects?
Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.
Which types of radiation are harmful to humans?
Ionising radiation includes both electromagnetic sources, such as X-rays and gamma rays, and particles, such as alpha and beta particles. Naturally occurring radon gas, for example, emits alpha particles. Ionising radiation can cause burns, radiation sickness, and cancer.
What are the two types of radiation effects?
Non-Ionizing and Ionizing Radiation There are two kinds of radiation: non-ionizing radiation and ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms.
What are the effects of radiation on the environment?
Plants and animals within the affected area take up radioactive particles, and these move through the ecosystem through bioaccumulation. Radiation pollution within waterways also accumulates within fish and other aquatic organisms, and runoff from radiation within the soil provides additional contamination.
What are the 4 types of radiation?
There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. The first is an alpha particle.
What are the 3 main types of radiation?
The three most common types of radiation are alpha particles, beta particles, and gamma rays.
What are 5 harmful effects of radiation?
Radiation Effects on Humans
| Dose (rem) | Effects |
|---|---|
| 5-20 | Possible late effects; possible chromosomal damage. |
| 20-100 | Temporary reduction in white blood cells. |
| 100-200 | Mild radiation sickness within a few hours: vomiting, diarrhea, fatigue; reduction in resistance to infection. |
What are the 7 types of radiation?
The electromagnetic spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV) light, X-rays and gamma-rays.
What causes radiation in the environment?
The majority of background radiation occurs naturally from minerals and a small fraction comes from man-made elements. Naturally occurring radioactive minerals in the ground, soil, and water produce background radiation.
