Editing Radioactivity (section)

== Safety Precautions ==

* This demonstration utilizes a Dosimeter, which needs to be carefully taken care of. Remove the batteries from it when it is no longer in use to preserve battery life. It is a sensitive piece of equipment, so never drop it or you may disrupt the equipment inside. If you notice that the batteries are low, be sure to plug the device in when you return to the planetarium, and allow it to charge overnight. Do not leave it plugged in for more than 24 hours.
* This demonstration uses radioactive materials. Be careful not to let small children put '''anything''' from this demonstration in their mouths. Make sure that students know to wash their hands after this demonstration if they handled any of the samples.
* '''''Do not let anyone keep any of the radioactive samples'''''. The pieces are safe to hold and examine, but be sure to have all pieces returned to you before the end of the demonstration. 
* The plate gives off Beta-decay and Alpha-decay at moderate levels, so it should be kept in the plastic basin until needed during the presentation. The Uranium ore sample gives off Beta-decay and Alpha-decay as well, but at much lower levels, and can be kept out of the bin during the performance. The Trinitite gives off Alpha-decay. All the samples are safe to handle.
* All Science Theatre Officers who will be using this demonstration should go through the [http://www.oeos.msu.edu/TRAIN/RDR/ EHS Radiation Safety Refresher Training]. Officers and volunteers are not required to go through this training, but officers are strongly encouraged to do so. Officers are required to instruct volunteers on safe handling of radioactive samples, the Dosimeter, and proper presentation of this demonstration.
