Alpha Beta Crosstalk: Ludlum 3030P Impact on Alpha Counts?

[Bigjoemonger]

I have a Ludlum 3030P alpha beta counter. This has windows set from 70 - 700 mV and 1000 - 4000 mV but i only use it to measure Alpha smears. This instrument comes optional with detector shielding which reduces background betas. Since I'm not measuring betas does it matter that I don't have the shielding?

I know that there is some beta to alpha crosstalk but would allowing this background beta in significantly impact my alpha counts?

Yes, it can have an impact on your alpha counts. The shielding is designed to reduce the amount of background beta radiation that can interfere with your alpha readings. Without the shielding, you may be receiving more background beta radiation than is necessary and this could result in a higher count rate than what is actually present. It is important to have the shielding in place to ensure accurate readings.

It is always best to use the appropriate shielding for your instrument, even if you are only measuring alpha particles. While the beta particles may not be directly affecting your alpha measurements, they can still contribute to background noise and potentially affect the accuracy of your results. Additionally, using the proper shielding can help prolong the lifespan of your instrument. It's always better to err on the side of caution and use the recommended shielding for your Ludlum 3030P alpha beta counter.
