 Trim off the wire ends, to enough room for the pins to go into the irradiator. You may need to bend the ends to fit. Trim off the wire ends, to enough room for the pins to go into the irradiator. You may need to bend the ends to fit.

 The second person can hold the pin in place with the scissor-style tweezers. We used a shallow box so that we could rest the tip of the tweezers against the bottom while holding the pin in the groove. The second person can hold the pin in place with the scissor-style tweezers.

 Before using the pin sources, you should measure the radiation with the digital radiometer.  Pins reading higher than 300 cpm at 5 cm away may be too strong. Record the radiation level at both 5 cm and 1 cm away along with the corresponding number on the plastic pin source holder. Later, record the telescope number corresponding to each pin source number. Before using the pin sources, you should measure the radiation with the digital radiometer.  Pins reading higher than 300 cpm at 5 cm away may be too strong.

 Before you throw anything out, remember that anything that has touched the pin sources may now be radioactive.  Test your materials, even trash, with the radiometer before putting them away.  The half-life of the pin sources is short, so you can store radioactive items in the safe for a few days and retest them later. Before you throw anything out, remember that anything that has touched the pin sources may now be radioactive.  Test your materials, even trash, with the radiometer before putting them away.  The half-life of the pin sources is short, so you can store radioactive items in the safe for a few days and retest them later.
