What diseases can you get from nuclear radiation?
At lower doses, ionizing radiation can cause health effects such as cardiovascular disease and cataracts, as well as cancer. It causes cancer primarily because it damages DNA, which can lead to cancer-causing gene mutations.
What are 3 harmful effects of radiation?
How Radiation Affects Your Body. Radiation can damage the DNA in our cells. High doses of radiation can cause Acute Radiation Syndrome (ARS) or Cutaneous Radiation Injuries (CRI). High doses of radiation could also lead to cancer later in life.
What are the 3 types of harmful radiation?

What are the 2 types of radiation damage?
Non-Ionizing and Ionizing Radiation Ionizing radiation has so much energy it can knock electrons out of atoms, a process known as ionization. Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes.
What is most affected by radiation?
Lymphocytes (white blood cells) and cells which produce blood are constantly regenerating, and are, therefore, the most sensitive. Reproductive and gastrointestinal cells are not regenerating as quickly and are less sensitive. The nerve and muscle cells are the slowest to regenerate and are the least sensitive cells.

What is the effect of ionizing radiation on cells?
While cells are damaged by free radicals all the time, they normally repair themselves, keeping the body healthy.
What happens when cells are exposed to radiation?
When cells — and what lies within them — get exposed to radiation, components of DNA and critical proteins within the cell get all jazzed up (ionized), meaning that the electrons with our atoms get kicked out, causing the DNA strands to break and the proteins to cramp up (denature).
How long does it take to die from radiation?
It's nearly impossible to predict the threshold of exactly how much radiation you would need to be exposed to in order to die, but according to the US Nuclear Regulatory Commission, "It is believed that 50 percent of a population would die within 30 days after receiving a dose of between 3500-5000 mSv (3.5-5 Sieverts) to the whole body, over a period ranging from a few minutes to a few hours."

Reproductive organs. Rapidly dividing cells (eggs and sperm) in the ovaries and testes can die, leading to sterility.
How quickly can radiation kill you?
As the radiation dose gets higher (many sieverts) this can kill you very quickly, in a matter of hours if the dose is high enough.". "It works exactly the same as lower doses of radiation but on a mass scale and when enough cells die that can cause problems", says Crossley.

Types of ionising radiation include: Alpha particles — two protons and two neutrons bound together like a helium nucleus — are large particles that can do lots of damage, but only over short distances. Beta particles — are electrons, which can travel longer distances in air and tissue than alpha particles.
What happens when neutrons are smashed into an atom?
In a reactor when neutrons are smashed into an atom, the atom releases neutrons which then hit other atoms in a chain reaction (find out how nuclear reactors work).

According to Crossley, there are two ways you can be exposed to radiation.
Is radiation harmful to humans?
The amount of radiation harmful to people depends on which chemical element, and how much of it they are exposed to, says Steven Crossley, a radiation physicist at Sir Charles Gairdner Hospital in Western Australia. Different variations of elements, known as isotopes, decay by different methods and give off different types of radiation, ...
How long has radiation been studied?
minus. Related Pages. Scientists have been studying the effects of radiation for over 100 years; so we know quite a bit about how radiation interacts with living tissue, and its effect on the body.

We know that radiation at high doses can cause cancer, could harm fetuses, and can even lead to death. Learn more about dose and health effects of radiation.
How does nuclear radiation affect living cells?
Atomic bombs and nuclear reactors all emit ionizing radiation which affects living cells by damaging their genetic material (DNA). Fortunately, our body cells are effective in repairing such damage. However, if the body isn’t sufficient enough to guard itself against this radiation then the cells may die or cause them to mutate in ways that eventually lead to cancer. Exposure to nuclear radiation can also result in skin burns, acute radiation syndrome, and long term cardiovascular disease.
What is Nuclear Radiation?
This is a form of radiation energy emitted by radioactive decay which can appear as high-speed particles. There are several types of radiations; beta, alpha, gamma, and x-ray. The beta exhibit itself in the form of electrons, alpha is made of two protons and two neutrons while gamma and x-ray appear as waves.
What happens to thyroid if it is exposed to radiation?
Thyroid: As a result of radiation malfunctions, radioactive iodine is released to the atmosphere. Thyroid happens to be the most sensitive part to this radiation . The radioactive iodine is absorbed by the thyroid leading to thyroid cancer. Since radioactive iodine has a high affinity for the thyroid, specialists are taking this advantage and attracting this radiation for therapeutically uses and to treat thyroid cancer.

How much radiation is needed to cause acute radiation syndrome?
Imagine getting radiation from 18,000 chest x-rays distributed over your entire body in a short period of time. This is how much radiation is required to cause acute radiation syndrome no wonder it can easily lead to death. Cases of acute radiation syndrome are rare and come from extreme events such as nuclear explosions or accidental rupture of a highly radioactive source.
What are the effects of radiation exposure?
It can also result in long-term health effects such as cancer and cardiovascular disease. Exposure to low levels of radiation encountered in the environment does not cause immediate health effects, but is a minor contributor to our overall cancer risk.
How does ionizing radiation affect cells?
Ionizing radiation Ionizing radiation Radiation with so much energy it can knock electrons out of atoms. Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. has sufficient energy to affect the atoms in living cells and thereby damage their genetic material (DNA). Fortunately, the cells in our bodies are extremely efficient at repairing this damage. However, if the damage is not repaired correctly, a cell may die or eventually become cancerous. Related information in Spanish (Información relacionada en español).
What is the term for radiation sickness?

It takes a very high radiation exposure to cause acute radiation syndrome —more than 0.75 gray gray A gray is the international unit used to measure absorbed dose (the amount of radiation absorbed by an object or person).
What is radiation risk?
Radiation risk may refer to all excess cancers caused by radiation exposure (incidence risk) or only excess fatal cancers (mortality risk). Risk may be expressed as a percent, a fraction, or a decimal value.
