Cobalt-60 is a very strong gamma emitter and as such is hard to shield. Direct handling is likely to be fatal. Even dozens of feet away from a bare sample of large enough size could expose you to LD50 levels and you will need medical treatment to recover from the radiation poisoning.
Cobalt-60 is commonly used for food irradiation, to kill dangerous organisms. In this case workers operate behind thick leaded concrete shields and the food passes by the sample on conveyer belts. In particular dried spices are treated this way.

What are the causes of the radiological accident in mayapuri?
A cobalt-60 from Delhi University, which was unused for 25 years, was sold to unsuspecting scrap dealers. They then dismantled it and due to the harmful radiation emmited by the cobalt-60 pencils, there were 5 people who were exposed to radiation in which one died.
What is the equation for transmutation of cobalt?
Cobalt-60 decay to nickel-60:Co-60------------Ni-60 + 1 electron + 1 neutrino + gamma rays
How many neutrons does a cobalt-60 atom have?
Since cobalt has an atomic number of 27, any isotope of it contains 27 protons and 27 electrons per atom. The isotope with mass number 60 contains (60 - 27) or 33 neutrons per atom.
Is cobalt 60 natural?
no it not natural it sythentic
What is the half-life of Cobalt-60?
Half-life of Co-60 = 5,27 year by beta- emission (0.315 MeV max.)
How is cobalt-60 radiation useful in preseving fresh fruits and vegetables?
Gamma radiation destroy harmful microorganisms and insects.
Does cobalt cause pollution?
Cobalt is more of a concern for industrial exposure (for workers) In nature there are few cases of cobalt exposure having any harmful effects. One Ontario brewery added cobalt as a foam stabilizer which caused some problems in heavy consumers.
If cobalt-60 emits a gamma ray what is the product?
Cobalt-60

Is cobalt harmful to people?
Yes, it is.
What is the half -life of cobalt-60?
Cobalt-60 has an 1/2 life of 5.24 years
How is cobalt 60 and cobalt 59 the same element but have different mass numbers?
Cobalt 60 has an extra neutron buit that does not affect chemical properties
What is the equation for transmutation of cobalt?
Cobalt-60 decay to nickel-60:Co-60------------Ni-60 + 1 electron + 1 neutrino + gamma rays
What is the average cost for the cobalt 60?
Cobalt 60 is a radioactive chemical not usually available for sale. Cherolet manufactures the car Cobalt, which can accelerate from 0 to 60 mph in 5.2 seconds. Its cost is about $30,000.
Is cobalt-60 suitable for treatment?
Cobalt 60 is a very valuable radiation source for the treaments of many types of cancers.
