Let's learn about radiation sickness caused by exposure to high doses of radiation!

We are all a little scared of the word “ Radiation ”, right? Sometimes we think that this is a very dangerous thing. However, today we are not going to talk about ordinary radiation. We are talking about a serious health condition that can occur if our body is exposed to very high, that is, high doses of radiation. This is what doctors call “Radiation Sickness” or `(Radiation Sickness)`. Some people also call it `( Acute Radiation Syndrome – ARS)`. This is something that can really be life-threatening. So, let’s find out more about this, shall we?

What is this so-called radiation sickness? Simply put…

Simply put, this is a serious illness caused by exposure to high levels of ionizing radiation , either all at once or over a short period of time. You may have heard that ionizing radiation is used to generate energy in some industries, power plants, and military applications. It is also used in very small, controlled doses in some medical treatments, such as radiation therapy for cancer patients.

However, radiation sickness is usually associated with sudden and severe exposure to radiation. Think of it this way, like an accident at a nuclear power plant. The severity of this condition depends on several factors:

• The amount of radiation absorbed by your body: This is measured in units called “Grays” (Gy). The higher the amount, the greater the damage.
• How long you were exposed to radiation: A large dose over a short period of time is much more dangerous than small doses over weeks in the same area of ​​the body (such as cancer treatment ).
• Whether the whole body was exposed or just a part of the body: If the entire body is exposed to a large amount of radiation at once, it can cause death within a few hours or even months.

Think of the cells in our bodies as little houses. When exposed to a small amount of radiation, those houses can make small repairs. But if a sudden, massive radiation attack comes, it's as if those houses are completely destroyed.

What are the main types of radiation sickness (ARS)?

After a single exposure to a high dose of radiation, three main syndromes (i.e., a collection of symptoms) can occur.

1. Cerebrovascular syndrome: This is when blood flow to your brain is affected . This occurs when the whole body receives a very high dose of radiation (greater than 30 Grays (>30 Gy)). This is a very serious condition.

2. Gastrointestinal (GI) syndrome: This is damage to your digestive system . This condition can occur if you receive a total body radiation dose of between 6 and 30 Grays (approx. 6-30 Gy).

3. Hematopoietic syndrome: This affects the production of all types of blood cells in our body. This can occur if the whole body receives a radiation dose of between 1 and 6 Gray (approx. 1-6 Gy).

All of these types are dangerous, but the severity is determined by the radiation dose.

How common is this? Should we be afraid?

In fact, radiological or nuclear emergencies that can lead to radiation sickness are very rare . But if they do happen, they can affect a large number of people at once. The worst events in our memory are the atomic bombings of Japan during World War II and the Chernobyl disaster in 1986. In addition to those who died immediately, thousands of people later died from radiation-induced cancer. So, while this is rare, it is very serious when it happens.

What are the symptoms of radiation sickness? How do you recognize it?

Symptoms may begin immediately after exposure to radiation, or they may appear days, weeks, or even months later. Although symptoms vary depending on the type of syndrome mentioned above, there are some common early signs :

• Feeling extremely tired and weak
• Nausea and vomiting (maybe vomiting blood )
• Rectal bleeding (bloody stool)
• Diarrhea (vomiting)
• Fever
• Feeling confused, disoriented
• Hair loss
• Skin pain, discoloration, swelling, or a burning sensation

These are the first signs to appear. Then, symptoms and complications related to the three syndromes discussed earlier begin to emerge.

What are the stages of radiation sickness?

There are several distinct stages of acute radiation syndrome (ARS). They are:

1. Prodromal stage: The first symptoms (such as the aforementioned nausea and vomiting) begin within a few minutes to two days after exposure to radiation.

2. Latent asymptomatic stage: This is a strange time. After the initial symptoms have subsided, you can go from a few hours to about 21 days without any symptoms. You may even feel as if you have recovered from the disease.

3. Systemic illness stage: This is when severe symptoms and changes in the body begin. This can begin within a few hours to less than 60 days of exposure. Symptoms vary depending on the type of syndrome.

Why does radiation sickness occur? What are the causes?

The main cause of this radiation sickness ``Acute Radiation Syndrome`` is direct exposure to high doses of radioactive materials or contamination with them ``(contamination) . Think about it this way: Low doses of radiation can interfere with the repair systems, growth, and division of our cells. However, large doses cause cells to die .

Direct exposure can occur from things like nuclear explosions, radiation accidents, and radioactive fallout from nuclear weapons testing. Contamination can also occur through eating and drinking food or water contaminated with radioactive substances, and through skin contact with radioactive materials.

Is this a contagious disease? `(Is ARS contagious?)`

This is a question that many people ask. Imagine that if someone is exposed to a high dose of radiation and then they are properly ``decontaminated`` – that is, if they remove their clothes and wash their body thoroughly with soap – you will not get radiation from them. Because the radiation is ``internalized`` inside their body.

However, if you are around someone who has not been decontaminated, you are also at risk of radiation poisoning . For example, first responders in a nuclear emergency are at higher risk.

How do doctors diagnose this?

Doctors diagnose radiation sickness by considering the following factors:

• History of radiation exposure: That is, details such as whether you have encountered such an incident and how it happened.
• Symptoms and signs: What are your symptoms, when did they start, and how severe they are.
• Laboratory test results: In particular, a complete blood count (CBC) is performed, and the results are monitored over time to determine the radiation dose and what to expect in the future (prognosis).

If there is a suspicion of contamination with radioactive materials, doctors use a device called a Geiger-Muller counter to check the entire body for ionizing radiation and how much is present. To check for radioactive materials that have entered the body, swabs are taken from areas such as the ears, mouth, and wounds and tested with this counter. Sometimes urine and feces can even be tested for radioactivity.

What are the treatments for this?

Treatment for radiation sickness varies depending on its severity. Because such a large radiation exposure occurs in an emergency, doctors and emergency services prioritize treatment based on the severity of symptoms and injuries.

The following are the common treatments:

• Decontamination: Removing your clothes and washing your body thoroughly stops the spread of radiation to others. This is very important.
• Surgical procedures: If there are life-threatening injuries, surgery may be necessary.
• Supportive care: This includes giving the body fluids and electrolytes it needs, giving medications to reduce pain from burns or other injuries, and giving antibiotics if there are signs of infection.
• Prevention of thyroid cancer: Doctors usually recommend potassium iodide tablets for all children and pregnant women who have been exposed to radiation. This prevents the absorption of radioactive iodine into the thyroid gland.
• Management of psychological trauma: This can be a major psychological trauma when faced with something like this. This can be treated with psychotherapy ( talk therapy) and, if necessary, medication.

Are there ways to avoid radiation sickness? (Prevention)

There is really nothing we can do to prevent unexpected high radiation exposure and radiation sickness. However, there are some steps you can take to protect yourself in the event of a nuclear emergency:

• Leave the area of ​​exposure immediately: Leave the area of ​​radiation exposure as quickly as possible. Do not re-enter.
• Decontaminate immediately: Remove contaminated clothing as soon as possible and place in a tightly sealed container. Wash your body thoroughly with soap and water.
• Seek immediate medical attention: It is essential to seek emergency medical attention as soon as possible.

What happens if this happens? Will it get better? `(Prognosis)`

The outlook for radiation sickness depends on several factors:

• How much radiation was absorbed by your body.
• How much of your body was affected.
• Whether you were able to get medical treatment quickly.

Radiation sickness is often a fatal condition. As the radiation dose increases, the time to death decreases.

However, even survivors can have long-term complications . In particular, there is an increased risk of developing radiation-induced cancers, such as leukemia and thyroid cancer .

When should we seek medical advice?

If you are exposed to a high dose of radiation, it is always an emergency and requires immediate medical attention . Get away from the radiation source as quickly as possible and get help as soon as possible.

So, what are the most important things we need to remember? (Take-Home Message)

Okay, we've talked a lot about radiation sickness. Here are some key things to remember:

• Radiation sickness is a serious, life-threatening condition caused by exposure to high doses of radiation.
• Things like this happen very rarely , but when they do, the consequences are dire.
• Early symptoms may include severe fatigue, nausea, vomiting, diarrhea, fever, and hair loss .
• If you encounter a radioactive incident, if possible, first remove your clothes, wash your body thoroughly with soap and water, and ``decontaminate`` .
• Then, seek medical attention immediately , as early treatment is more likely to save your life.

I hope this information is useful to you. It's always important to be aware of things like this. Be careful!
