Radioactive elements.
It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.
Polonium-210 primarily emits alpha radiation, which consists of two protons and two neutrons. This type of radiation has a low penetrating power and is highly ionizing, making it hazardous if ingested or inhaled.

Group 1 elements, such as lithium, sodium, and potassium, easily give up electrons because they have one electron in their outer shell and are highly reactive. Additionally, elements in Group 17, such as fluorine and chlorine, can also easily gain electrons.
Group I (alkali metals) and Group II (alkaline earth metals) elements on the periodic table are more likely to give away electrons to form positive ions. These elements have one or two electrons in their outermost energy level, making it easier for them to lose these electrons and achieve a stable electron configuration.

Radioactive elements give off radiation. The emission of radiation occurs when an unstable atomic nucleus tries to become stable. Some examples of radioactive elements are radium, curium, nobelium, rubidium, and polonium.

Yes, humans give off a very small amount of radiation due to the natural radioactive decay of elements within our bodies, such as potassium-40. This radiation is very low in level and not harmful to others.
Radioactivity.
Examples of radiation can be found in various contexts, such as sunlight (solar radiation), X-rays used in medical imaging, and radiation produced by radioactive elements like uranium. Additionally, natural sources of radiation can be found in rocks, soil, and even the human body.
Yes, unfortunately it is true because the way in which some cancers are treated is with radiotherapy. Radiotherapy is a form of ionising radiation like x-rays, and as a result, when that ionising radiation goes through your body, it does damage cancer cells, and it tends to damage cancer cells more than healthy tissue because cancer cells are more vulnerable to damage because they don't have such good DNA repair mechanisms. But the point is, it can still damage healthy tissue.And so, in the course of dealing with one tumour, it can increase the risk - it doesn't necessarily give you cancer - but it can increase the risk of developing another type of cancer. Very often, bone can be targeted or bone marrow cells, and therefore, you can get secondary tumours developing later in life as a consequence of having been treated.But if you take certain chemotherapy drugs, they don't necessarily have that same risk. They're not ionising radiation, so it depends on the kind of treatment that you get.
Marble countertops can emit low levels of radiation due to the naturally occurring radioactive elements present in the stone, such as uranium and thorium. However, the amount of radiation emitted is typically considered to be negligible and not harmful to human health.
Radiation
Granite countertops do emit low levels of radiation due to natural radioactive elements like uranium and thorium that are present in the stone. However, the amount of radiation is typically very minimal and considered safe for everyday use. It is recommended to use a sealant to minimize any potential risk.
All cell phones give off varying degrees of radiation.
