Time, distance and shielding. I'm guessing this is from IS 3 radiological emergency management. You can just get the guide off of femacourses.com, or you can read through the course for the answer at training.fema.gov.
The three key factors important in protecting individuals from radiation are time, distance, and shielding. Reducing the time spent near a radiation source decreases exposure, while increasing the distance from the source significantly lowers radiation intensity due to the inverse square law. Additionally, using appropriate shielding materials can effectively absorb or block radiation, further minimizing exposure risks. Together, these factors help ensure safety in environments where radiation is present.
The three main factors that influence the amount of solar radiation received at a location are the angle of incidence of the sunlight, the length of the day, and atmospheric conditions like cloud cover or air pollution. These factors affect how much sunlight reaches the Earth's surface and can impact the intensity of solar radiation.

The half-life of the radioactive material, the type of decay process, and the initial quantity of radioactive material are physical factors that do not affect the amount of radiation emitted by a radioactive source. Radiation emission is solely determined by the intrinsic properties of the radioactive material itself.

No, beta radiation is not the heaviest of the three types of radiation. Alpha radiation consists of heavier particles (helium nuclei) compared to beta radiation, which consists of fast-moving electrons. Gamma radiation is the most penetrating and has no mass.
Three key factors that help keep a climate balanced are solar radiation from the sun, greenhouse gases in the atmosphere that trap heat, and the Earth's surface features like mountains and oceans that influence weather patterns. These factors work together to maintain a relatively stable climate system on Earth.
Radioactive substances release three kinds of radiation depending on their type. They can release alpha, beta, or gamma radiation. While they are all harmful, gamma radiation is the most so. Radiation can alter the DNA of the cells which it comes into contact with, causing mutations. One must protect oneself from radiation because these mutation are likely to result in cancer, which is a problem that can start in one cell and move to others and causes severe health problems.
Conduction, Convection, Radiation
There are three. In order of the amounts they protect us: # nitrogen, absorbs UV-C and more energetic radiation, ~78% of the atmosphere # oxygen, absorbs UV-C and more energetic radiation, ~21% of the atmosphere # ozone, absorbs UV-B and more energetic radiation, ~0.0001% of the atmosphere
Individual sensitivity Radiation dose absorbed type of radiationRadiation sickness varies based on the amount of expsure of radiation and how particular person's body reacts to the radiation poisoning. It also depends on how the radiation poisoning entered the body: Oral, inhalation or total body exposure.
The three main types of radiation are alpha radiation, beta radiation, and gamma radiation. Alpha radiation consists of alpha particles, beta radiation consists of beta particles, and gamma radiation consists of gamma rays.
