1. Retarded concepts
: Parent substance, daughter substance, rate of decay, disintegration or decay constant, counting rate, mean life, disintegration product.


2. Principle and task
: The half-life of a Ba-137 m daughter substance eluted (washed) out of a Ca-137 isotope generator is measured directly and is also determined from the increase in activity after elution.

Connecting cord, 500 mm, blue 07361.04 1


4. Problems

1. To record the counting rate as a function of the counter tube voltage (counter tube characteristic) when the isotope generator activity is constant (radioactive equilibrium).

2. To measure the activity of the isotope generator as a function of time immediately after elution.

3. To measure the activity of a freshly eluted solution of Ba-137 m as a function of time.
