Lead Shot Bags
It is advised that you have at least two 2Kg bags of lead shot as part of your emergency kit and two 5Kg bags if you are using Co 60.
Lead Shot 2 kg Bag
2Kg bags offer a compromise between flexibility, mass and attenuation. These bags are normally used for Yb169, Se75 and Ir192.
Lead Shot 5 kg Bag
5Kg bags offer the maximum attenuation for a very high energy isotope.
