With some film and a saltshaker , you’re able to take radioactive picture .
Everyone bang idle exposes film , but other anatomy of radioactivity do as well - a fact you could practice to take pictures in some pretty unusual ways .
It ’s also how radiation was first discover . In 1896 , Gallic physicist Henri Becquerel salt away some x - beam film in a draftsman along with a U rock . He suspected that uranium might let out strange rays when break to sunshine , but this sample had been keep entirely in the dark , so he was surprised to regain , on developing it , that the mineral had exposed the moving-picture show . The discovery of lifelike radiation come through him a Nobel Prize .
It ’s not gruelling to repeat Becquerel ’s experience at place with stock film . I took asunder a 10 - pack of Fujifilm ISO 3000 instant cinema and wrap each small-arm in tin foil . This must be done in downright darkness because 3,000 - amphetamine film is highly sensible . ( I sacrificed the first pack practicing in the light . )
Next I set a big , flat butterfly stroke - shaped earring directly on top of the wrapped film . I debar the most radioactive thing I have , a minuscule atomic number 88 puck from an old classroom curing , several inches above the earring . This allowed the radiation to glow through it and onto the film , exposing it justly through the transparency peignoir . Then I make grow the film by pulling it through the rollers of an old Polaroid tv camera ( once again , in everlasting darkness ) .
This exposure took about 36 hours , find by visitation and lots of error . If you ’re willing to wait longer , less - radioactive germ work too , even rough-cut salt replacement . Yes , atomic number 11 - innocent salt ( potassium chloride ) is sufficiently radioactive ( from the isotope potassium-40 ) that after several months , a salt shaker - ful will form an image on cinema . Provided you do n’t forget and eat the radioactive source on your breakfast .
Achtung ! Stronger radiation sources such as Ra vigil hands , and any source that ’s flake off fine particles , should be handled with care to denigrate picture and fend off taint .
