No fallout likely from Cosmos 1900

No-bang Quantum State of the Cosmos *

A quantum state of the entire cosmos (universe or multiverse) is proposed which is the equal mixture of the Giddings-Marolf states that are asymptot-ically single de Sitter spacetimes in both past and future and are regular on the throat or neck of minimal three-volume. That is, states are excluded that have a big bang or big crunch or which split into multiple asymptotic de Sitter spacetimes. ...

Iodine-131 Fallout from Underground Tests II.

In a recent report (1), List, Telegadas, and Ferber take issue with my earlier conclusion (2) that vented underground tests in Nevada were the probable sources for the repeated occurrences of iodine-131 fallout in midwestern United States during May 1962. In doing so they provide no evidence to establish that the underground shots in question were contained, but they suggest that precipitation ...

Pu isotopes in soils collected downwind from Lop Nor: regional fallout vs. global fallout

For the first time, soil core samples from the Jiuquan region have been analyzed for Pu isotopes for radioactive source identification and radiological assessment. The Jiuquan region is in downwind from the Lop Nor Chinese nuclear test (CNT) site. The high Pu inventories (13 to 546 Bq/m(2)) in most of the sampling locations revealed that this region was heterogeneously contaminated by the regio...
