Their results showed that when cesium-137 was used, the battery generated 288 nanowatts. Yet with the much stronger isotope cobalt-60, the battery produced 1.5 microwatts of power, about enough to switch on a tiny sensor.

Makes sense, cesium-137 has a half-life of 30 years, cobalt-60 has a half-life of 5.2 years.

This was basically proof of concept.

Now they can make a battery that can light an LED..............

A little off topic, but when gamma sterilization with cobat-60 was being developed researchers experimented with insane radiation doses.

Like 500-900 kGy.

Needles to say anything that wasn’t ceramic or metal came out as a black crisp.

You couldn’t even use what survived because the packaging was destroyed.
