Helium-3 emission from Nevado Del Ruiz Volcano, Colombia

High helium‐3/helium‐4 ratios, up to 6.6Ratm (6.6 times the atmospheric ratio of 1.40 × 10−6) were observed in nine samples of gases and hot waters from seven sites located around the volcano Nevado del Ruiz, Colombia. The values of the ratio decrease with distance from the crater. Such a tendency c...
