Scientists Just Built a Battery That Never Needs Charging

[Old Crank]

25. Me thinks,

My wife would disagree, that he is joking.

I did a bunch of radiation surveys while at my last job.
Alpha radiation you need a special detector not a regular Geiger counter. Most Alpha contamination was discovered with wipes and then in a scintillation counter. You skin blocks Alpha. Don't get it inside you.

Beta, regular counters work, most people in the labs worked with it behind 1/4 - 1/2 inch plastic shields. Stored in plexiglass boxes.

Alpha. Easily detected. I could use a counter and locate where it was stored in a refrigerator from the outside if not stored in lead.

Fun fact. A couple of the old radioactive EXIT signs had more Alpha radiation than our university's permit allowed for Alpha radiation.
