Abstract
- New alpha counters make accurate measurements of low emissivity samples possible. Modeling results set lower limits for measurements at sea level of silicon substrates to about 0.3\ \alpha/\ khr-cm^2. Our measurements demonstrate the effect of cosmic ray shielding on the measured alpha-particle emissivity. A few atoms of radon contamination can cause elevated emissivities many days after exposure.
