No. -- The heat from the fireplace is dangerous only if you sit too close.
-- The light from the flashlight is dangerous only if you hold it
2 inches from your eye.
-- The radiation from the TV station is dangerous only if you're
up on the tower in just the right place.

∙ 15y agoYes and no, radiation is what makes something radioactive, but in itself, people don't usually refer to it as being radioactive, since it is already referred as radiation.

left behind from what? A nuclear reactor? The waste from a reactor?
Wiki User
∙ 13y agoLike all types of radiation (including the visible-spectrum radiation being emitted by your computer screen as you read this sentence), yes.

Are meteorites ever radioactive?
Everything emits some amount of radioactivity. SO, the strictest answer is that they always do.
Are radioactive materials dangerous?
They can be. Some radioactive elements are chemical poisons, apart from their radioactivity, but beyond some fairly low level, the radiation itself can damage cells and tissues. High radiation doses can cause biological tissues (that's US!) to break down fairly quickly causing rapid death, and moderate radiation doses can cause cancers which can kill you over longer time periods. Low doses of radiation are probably harmless; the level of "low" is a matter of some dispute among scientists and doctors.
Can radiation-feeding bacteria eliminate radiation?
Not yet. There are no known species that can eat fast enough to keep up with it, so a substrantial portion of the radiation always gets through.
What direction is cyclonic flow and what pressure are associated with this?
It is clockwise in the southern hemisphere and counterclockwise in the northern hemisphere. Cyclonic flow is always associated with low pressure systems.
What is Radiation that is not a particle?
Radiation will always remain a particle so long as it doesn't come in contact with MOST direct sunlight, or water. In that case, water becomes irradiated and the Particle becomes part of the water..answer 2 electromagnetic radiation - radio waves do not involve particles. Sound waves, heat, and UV light etc also are radiation. 'Radiation' is also used in biology, to describe the spread .
What is the concept of radioactivity that's always there?
This is probably a reference to what is called background radiation. Background radiation has a number of contibuting factors, but it is "always there" in some form or another owing to radioactive decay of radioisotopes and to cosmic radiation and its effects.
How was radioactivity developed?
Radioactivity was not developed, it has always existed. It was mostly the work of Madame Curie that paved the way for its use in many applications today. Unfortunately she died of radiation poison, though her work lives on.
Why do radiation detectors register counts even though no apparent source of radioactivity is in the area?
Radiation detectors register counts even though no apparent source of radioactivity is in the area due to the background radiaoactivity and radiation that is always present. There are high energy cosmic rays (gamma) from the Sun, low level alpha, beta, and gamma from fallout from various nuclear detonations and accidents over the years, decay processes from naturally occurring Uranium, radiation coming from our own bodies, in the form of Strontium, Cesium, Potassium, and others, and contamination processes that occur in power and processing plants. When building and calibrating sensitive detectors, we always measure the background radiation and subtract that from the measured results.
Is an element's atomic mass always indicative of its level of radioactivity?
no
Is radiation always effective in shrinking a brain tumor?
Theres always a chance that radiation will not work... as there is with any method.

Why would human hair be examined for radioactivity?
Well, there's always a possibility of anything emitting radioactivity once it has been around a radioactive source without gear/protection. All the best.

Is gamma less dangerous the further away you are?
No... No matter how far away the radioactivity will always be the Same and have the same effect
How is radiation conduction and convection?
energy will always be transferred
A phylum is always associated with?
The answer is; "Animals".
What A recession is always associated with?
Contraction
