What are the works of Antoine Henri Becquerel?
He discovered rays, invisible to the eye but NOT xray or cathodrays (have been discovered prior) but radioactive rays.
How many radioactive elements are discovered uptill now?
There are currently 38 radioactive elements that have been discovered. These elements have unstable nuclei that undergo radioactive decay, emitting radiation in the form of alpha particles, beta particles, or gamma rays.
What were 5 of Marie curie's major scientific works?
discovered polonium discovered the existence of radium found how to isolate the radium metal discovered that thorium was a radioactive element discovered that uranium rays give conductivity to the air surrounding them
What is the name for the emission of rays and particles by a radioactive material?
The name for the emissions of rays and particles by a radioactive material are called radioactive decay. There are many different types of radioactive decay that emit different rays and particles.
What type of rays do x rays transmit?
radioactive
What are the 4 radioactive rays produced?
You think probable to beta rays, gamma rays, alpha rays.
When food is irradiated with gamma rays from a cobalt-60 source does the food become radioactive?
No. Gamma rays will not make materials radioactive.
Which is not radioactive beta rays gamma rays or X-rays?
Both beta rays and gamma rays are the products of radioactive decay and are the result of changes in atomic nuclei. X-rays can be generated by using high voltage to accelerate electrons and slam them into a metal target, so they might be said to be non-radioactive.
What was the device with which Roentgen discovered x-rays?
Roentgen was a scientist who investigated radiation. ----------------------------------- He discovered x-rays. Took the first x-ray of his wife's hand, when she saw it she was upset and remarked something about seeing her death.
Radioactive rays are absorbed by which metals?
Lead is commonly used to absorb radioactive rays due to its high density and ability to effectively block radiation. Other metals such as tungsten and uranium can also absorb radioactive rays to varying degrees.
Who discovered ultraviolet rays?
Johann Wilhelm Ritter discovered ultraviolet rays
Are radioactive materials dangerous Explain?
yeah! almost all radioactive materials are dangerous, from these material radioactive rays are originated which are namely alpha,beta,gamma and when these rays strike to the body so it leave incurable burn,however its small amount is also harmful such as: the radioactive material named radium are found in varieties of wrist watches so its also harmful for human health X-Rays are electromagnetic rays and these are also harmful but not so much therefore physicians avoids for X-rays reports but in severe condition they are compel to do that advise There are two type of radioactive element one is natural radioactive and other is artificial radioactive element From natural radioactive element radioactive rays are always originated so,radioactive materials are dangerous even it is artificial or natural
