What ray does not affect the photographic plate?
Gamma rays do not affect the photographic plate as they are highly penetrating and pass through without creating an image.
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.
What are three physical factors that have no effect on the amount of radiation emitted by a radioactive source?
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.
How does the presence of copper wire wrapped around a magnet affect the magnetic field produced by the magnet?
When copper wire is wrapped around a magnet, it creates an electromagnet. This increases the strength of the magnetic field produced by the magnet.
What does not affect the half-life or a radioactive substance?
The temperature The total amount of the substance The addition of a catalyst ~
Why can a radioactive material affect photographic film even though the film is well wrapped in black paper?
Radioactive materials emit ionizing radiation, such as alpha particles, beta particles, and gamma rays, which can penetrate various materials, including black paper. This radiation can interact with the photographic film's emulsion, causing chemical changes that result in a latent image, even when the film is not exposed to visible light. The film's sensitivity to radiation allows it to detect these emissions regardless of the wrapping.
What ray does not affect the photographic plate?
Gamma rays do not affect the photographic plate as they are highly penetrating and pass through without creating an image.
What experiments did becquerel perform?
Henri Becquerel performed experiments that involved exposing uranium salts to sunlight and observing their ability to fog photographic plates wrapped in light-proof paper. He discovered that the uranium salts emitted radiation that could penetrate opaque materials and affect photographic plates. This accidental discovery led to the development of the field of nuclear physics.
Is an radioactive metal gold?
To some extent most elements are radioactive whenever there is a possibility of an unstable isotope. However, generally speaking, gold is not considered to be radioactive. Having said that, radioactive gold can be made.
How do x rays affect photographic plates?
X-rays will "Fog" photographic plates. That means the plates act as if 'exposed' to light. If the X-rays are intense enough, the plates will appear to be totally exposed.
Is computer heat radioactive?
Maybe, b'cos of the small amounts of radioactive materials used in them( NOT SO SURE). that may affect us.
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.
What does not affect the half life or a redioactive decay?
External factors such as temperature, pressure, and chemical reactions do not affect the half-life of a radioactive substance. The decay rate of a radioactive isotope remains constant over time regardless of these external conditions.
How do minerals containing uranium darken photographic film?
Uranium minerals emit radiation that causes silver halide crystals in photographic film to undergo a process known as fogging. This fogging results in darkening of the film, affecting the quality of images produced.
Why can the effects of radioactive decay on the body be useful and harmful?
Radioactive materials released from a source can affect the human body via a number of pathways. Some may be transported by winds or water to our vicinity. These radioactive substances can affect us through direct irradiation and may be inhaled or ingested.
How do radioactive wastes affect the Earth?
it can kill the earth and even us if there is to much
How do physical and chemical changes affect radioactivity?
They don't - which is why radioactive dating works.
