With a geiger counter. It can detect radioactive particles. That is the most common, modern way. In Ernest Rutherford's 'Gold Foil' Experiment, he visible saw radioactive particles by using a sheet of Zinc Sulfide that lit up when it was hit by an alpha particle (form of radiation).
You can tell if a substance is radioactive by using a Geiger counter, which detects ionizing radiation. Radioactive substances emit radiation that can be detected by the Geiger counter, indicating their radioactive nature. Additionally, measuring the levels of specific radioactive isotopes in the substance can provide further confirmation of its radioactivity.
It means that the atoms inside the substance are not stable; the nuclei in these atoms can decay. This changes one type of atom into another and releases radiation (the exact type of radiation depends on the substance). Types of radiation are gamma rays, electrons/positrons or helium nuclei.
use a gigacounter near the element i guess use a gigacounter near the element i guess
isotopes have the same number of neutrons. elements have the same number or neutrons
A chemical element is radioactive if this element emit radioactive radiations as alpha, beta or gamma; all artificial elements or isotopes are radioactive.

Was used as a target substance in the experiments by Irene joliot-Curie?
Beryllium was used as a target substance in the experiments by Irene Joliot-Curie.
What is the difference between radioactive and non radioactive materials?
Radioactive materials contain unstable atoms that decay and emit radiation, while non-radioactive materials do not emit radiation. Radioactive materials can be harmful to living organisms due to their ionizing radiation, whereas non-radioactive materials are generally considered safe for everyday use.
To use radioactive dating for a substance you must know the substances?
decay rate and initial amount of parent and daughter isotopes. By measuring the current ratio of parent to daughter isotopes in the substance, you can calculate how much time has passed since the radioactive decay began.
Half of the total amount of time it takes for all of a radioactive substance to decay is called the halflife of the substance?
okay
Is a proton a radioactive emission?
No, a proton is not a radioactive emission. Protons are stable particles found in the nucleus of all atoms. Radioactive emissions typically involve the release of particles such as alpha particles, beta particles, or gamma rays from a radioactive substance.
What is the difference between a non-radioactive substance and a radioactive substance?
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.
What affect the half life of a radioactive substance A the mass of the substance B the temperature of the substance C the addition of a catalyst D the type?
A. The half-life of a radioactive substance is determined by the specific decay process of that substance, so it is not affected by the mass of the substance or the temperature. B. The mass of the substance does not affect the half-life of a radioactive substance. C. The addition of a catalyst does not affect the half-life of a radioactive substance. D. The type of radioactive substance directly determines its half-life, as different substances undergo radioactive decay at varying rates.
Is radioactive waste a pure substance or a mixture?
Radioactive waste is nearly always a mixture but it is possible to be a pure substance.
What is a radio substance?
A radioactive substance emit nuclear radiations.
Is plutonium a radioactive substance?
Yes
Is Pm a radioactive substance?
Pm is Prometheum. All isotopes of this element are radioactive.
Can anyone give you an example of a radioactive substance?
H3, Deuterium is radioactive. Uranium and plutonium are radioactive and are used in atomic bombs.
What is a beta emitter?
In physics, an alpha emitter is a radioactive substance which decays by emitting alpha particles.
Is there any way to change the average amount of radiation emitted from a radioactive substance?
No, the average amount of radiation emitted from a radioactive substance is inherent to the substance's decay process and cannot be changed. The rate of decay is measured by the substance's half-life, which is a fixed characteristic of the radioactive material.
What does radioactive hazard mean?
That the substance is dangerous & explosive.
The original sample of a radioactive substance?
Yes, and the question is ... ?
What is the most common units used to express the activity of a radioactive substance?
The most common unit used to express the activity of a radioactive substance is the Becquerel (Bq). One Becquerel is equal to one radioactive decay per second.
