** Only registered users can order chemicals **

The Protactinium Generator brings the phenomenon of radioactive decay into the
classroom. With a half life of the order of a minute, students have the
opportunity to record a complete decay curve in a single lesson. An ideal
opportunity to use a datalogger with a radioactive count rate sensor to record
the activity, and compare it to a predicted decay curve. Protactinium234 has a
half life of about 70 seconds, and is ideal for the observation of radioactive
decay. The decay is monitored by a Geiger tube placed close to the top of the
container, supported by a stand and clamp. Over a period of 5 to 10 minutes a
clear half-life curve can be captured, manually or using a datalogger. Several
factors combine to ensure that Pa234 clearly exhibits its own half life. The
generator is supplied in a sealed translucent container, which is virtually
chemically inert with a leak-proof closure. This is packed in an outer
container which is suitable for long term storage. The generator can be stored
for a period of eight years, after which time disposal should be made through
a commercial disposal agency or via the local authority.
