Examples for everyday use
In the above table, TVT and TVL (and HVT and HVL) are the same quantity)
In the preceding sections of this handbook presentation we established the following which is recognised in modern radiation shielding literature.
- The TVL value for Co-60 in lead was shown to be 4 cm.
- The TVL value for Cs-137 in lead was shown to be 2.2 cm.
The values above were taken off the transmission curves shown earlier in this resource. It can be seen that the values are essentially the same as those presented in the above table.
