Because radiations emitted by radioactive elements decompose the components of the emulsion (AgBr).

What is considered an open fire?
An "open flame" refers to flame, usually used as a heating source, that is directly exposed to the outside elements, or often the object to be heated. Examples would include a Bunsen burner, a bonfire, or in some cases grills. The opposite would include heating elements that do not directly openly expose the flame, such as old stoves or heating elements.

What is the connotation to the word expose?
The word expose as a somewhat negative connotation, implying a non consensual exposure, one against the person's will. It implies vulnerability, which is negative.

What are two forces that can expose deeply buried fossils?
Erosion
How did Becquerel discovered radioactivity discovered radioactivity?
he noticed the first effects of radioactivity while he observed that with exposure to the sunlight the mineral gave off a penetrating energy that could expose film.
How did becquerels work lead to the discovery of two new elements?
Becquerel discovered radioactivity by accident while studying a mineral containing uranium. he observed that with exposure to sunlight the mineral gave off a penetrating energy that exposed the film. while one day he tried the experiment one day the day was cloudy so he put it away in a dark desk drawer and at the next day he found the picture of the mineral and later found out that the mineral did not need sunlight to expose radiation so he gave it to two young researchers that eventually isolated the two elements named polonium and radium

How did the physicist Becquerel first observe the effect of nuclear decay?
Becquerel was conducting experiments with phosphorescent minerals. Expose them to sunlight and they glow for a while. He placed these materials on photographic plates which had heavy paper on them to stop the sunlight from penetrating and exposing the plates. He prepares some photographic plates and it was overcast for several days and he could not do the experiment. He placed the plates in a desk drawer the first day and after several days of bad weather, decided to develop the plates anyway. They had been exposed. He looked in the drawer and it contained some ore samples containing uranium. The radioactive decay of the uranium had penetrated the paper coverings and had exposed the plates.
How long did it take to expose the first permanent photograph?
The first photographic process which was taken by Joseph Neipce took approximately 8 hours. However the daguerrotype, which was created by Louis Daguerre, was a new photographic process available to the public took approximately 30 minutes.
Why can red light be used in a dark room?
Dim red light will not expose black and white photographic film. Color film must be handled in total darkness.
What part of speech is expose?
Expose is a verb.
What is the prefix or suffix to expose?
to expose to danger
What is the prefix meaning for expose?
The "pose" part means "put". "Impose" means to put on something like a rule or a tax. "Counterpose" means to put something against something. "Superpose" means to put on top of something. "Depose" means to put off, out or away, by removing a ruler. "Expose" means to put out. You can put something out where people can see it, thus exposing it to their view. Or you can put something out in nasty weather, thus exposing it to the elements.
Is there enough residual heat at the Fukushima nuclear plants to reach 3000F and fully expose the uranium If so and maximum radiation reaches Tokyo what would be the level of destruction?
Specialists think that a more severe accident is not possible now at Fukushima.
