In no way, can radiation kill you instantly?
So long-term exposure to low doses of radiation increase the odds of getting cancer, while a single high dose will quickly cause immediate damage to cells and tissues — a process used effectively to kill tumour cells in radiation therapy.
At any event, can you survive radiation poisoning? A person who has absorbed very large doses of radiation has little chance of recovery. Depending on the severity of illness, death can occur within two days or two weeks. People with a lethal radiation dose will receive medications to control pain, nausea, vomiting and diarrhea.
For all that, can alpha radiation kill you?
alpha radiation is not as dangerous because it is unlikely to reach living cells inside the body. beta and gamma radiation are the most dangerous sources because they can penetrate the skin and damage the cells inside.
What is the first sign of too much radiation?
The initial signs and symptoms of treatable radiation sickness are usually nausea and vomiting. The amount of time between exposure and when these symptoms develop is a clue to how much radiation a person has absorbed.

A banana contains about 450 mg of potassium, and when eaten exposes the consumer to about 0.01 mrem due to its K-40 content. For comparison, a chest x-ray delivers 10 mrem.
On average, Americans receive a radiation dose of about 0.62 rem (620 millirem) each year. Half of this dose comes from natural background radiation. Most of this background exposure comes from radon in the air, with smaller amounts from cosmic rays and the Earth itself.
The Federal Communications Commission (FCC) — which regulates cell phones, among other things, in the United States — has set radiation standards for cell phones at 1.6 watts per kilogram averaged over 1 gram of tissue.
Take a warm shower and gently wash yourself with lots of soap. Do not scald, scrub, or scratch your skin. Your skin helps protect the inside of your body from radioactive material. Wash your hair with shampoo or soap.

Lead is fabricated into different product forms to provide radiation shielding and protection, and which includes these types:
- Lead Sheets, Plates, Slabs, & Foils.
- Lead Shot.

- Lead Pipe.
- Lead-clad Tubing.
In general, alpha particles have a very limited ability to penetrate other materials. In other words, these particles of ionizing radiation can be blocked by a sheet of paper, skin, or even a few inches of air.
Gamma rays have so much penetrating power that several inches of a dense material like lead, or even a few feet of concrete may be required to stop them. Gamma rays can pass completely through the human body; as they pass through, they can cause ionizations that damage tissue and DNA.
Staying inside will reduce your exposure to radiation.Close windows and doors.Take a shower or wipe exposed parts of your body with a damp cloth.Drink bottled water and eat food in sealed containers.
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.
In this type of brachytherapy, the radiation source stays in place for one to seven days.
