These lead shields are useful for safer storage. The school grade radioactive

sources are mounted in a 25mm diam. x 5mm thick plastic disc with the symbol

printed. Although radioactivity level is very low, the sources should not be carried

around for long periods or placed in pockets of clothing against one’s body.

Cat No:          Material:                    Particle:                   Strength:

PA2667-005 Polonium 210           Alpha particle            0.1 uCi or 3.7 kBq (+/- 1)

PA2667-010 Strontium 90             Beta particle              0.1 uCi or 3.7 Kbq (+/- 1)

PA2667-020 Cobalt 60                   Gamma particle        1.0 uCi or 37 kBq (+/- 10)

Useful conversion information:

1 Bq (Becquerel) = 1 disintegration per second = 27 x 10-12 Curie (Ci)

1 kBq = 27 x 10-9 nCi (nano Curie)

1 kBq = 27 x 10-6 uCi (micro Curie)

1 Ci = 37 x 109 Bq = 37 GBq (giga Becquerel)
 

CAUTION TO BE FOLLOWED:

These school grade radioactive sources have a very low level of activity and do not

require licensing, however they should be handled with care. The following rules

should be followed:

• Unnecessary handling of sources should be avoided. Do not place into

pockets of clothing or carry bags etc..

• As general practice, radioactive sources should always be handled with tongs

or forceps to keep them at least 30cm away from user.

• Handle the alpha source with special care to avoid damage to the fragile

metallic coating over the material.

• For Alpha sources, a thin aluminium sheet provides sufficient absorption.

• For Beta sources, about 4 to 6mm thick lead is required for full absorption.

• For Gamma sources, thick lead is required to absorb most of the radiation
