8:25 am INT RSSMC BG: 44.8 CPM^^
8:15 am INT RSSMC RAIN SAMPLE: 40.0 CPM^^ which is less than subsequent background, most likely a function of water’s natural radiation-blocking properties.

5:20 pm INT HEPA DUST from two HEPA filters, one Ionizer/HEPA filte from June 1 or 49 days minus five non-operational days totals 44 days: 51.7 CPM^^ which is background. This is an astonishing reading. It not only shows a long period of beta-free air but reinforces fact that high readings, such as the alpha-heavy last period ending June 1, 2015, are very troublesome and equally accurate. This is our first recorded HEPA dust test coming in at background in over four years of such sampling and testing.

11:45 am INT WALNUT CREEK, CALIFORNIA HOTEL: 31.9 CPM^^ [which is much lower than average background in Southern California perhaps due to extensive nuclear research and several partial experimental nuclear reactor meltdowns in region’s history.]

9:35 pm SAME RAIN SAMPLE IN PLASTIC BAG: 43.8 CPM^^ or 5.1 CPM alpha radiation. Alpha makes up 52.6% of overage.
Sample #4 – 9:20 pm RAIN: 48.9 CPM^^ or 24.7% HIGHER THAN BACKGROUND
9:00 pm INT RSSMC: 39.2 CPM^^
8:00 pm SAME RAIN SAMPLE IN PLASTIC BAG: 63.3 CPM^^ or 5.7 CPM alpha radiation. Alpha makes up 21.9% of overage.
Sample #3 – 7:45 pm RAIN: 69.0 CPM^^ or 60.5% HIGHER THAN BACKGROUND
7:30 pm INT RSSMC: 43.0 CPM^^
4:55 pm SAME RAIN SAMPLE IN PLASTIC BAG: 54.1 CPM^^ or 14.1 CPM alpha radiation ALPHA ALONE 34.8% HIGHER THAN BACKGROUND. Alpha makes up 50.9% of overage and is not the product of radon daughters/progeny as proved in Beta Watch.
Sample #2 – 4:30 pm RAIN: 68.2 CPM^^ or 68.4% HIGHER THAN BACKGROUND
4:15 pm INT RSSMC BG: 40.5 CPM^^

June 1, 2015
12:40 pm INT SAME HEPA DUST IN PLASTIC BAG – ALPHA TEST: 64.8 CPM^^ which suggests strong alpha radiation presence. A plastic bag will block alpha radiation meaning that of the background overage, beta was [64.8 – 41.5 =] 23.3 CPM^^. The total amount over background was [134.7 – 41.5=] 93.2 CPM^^. The amount of alpha radiation detected was this total minus the beta component of it [93.2 – 23.3 =] 69.9 CPM^^ The ALPHA RADIATION ALONE IS 168.4% OF BACKGROUND HIGHER which is astonishing.
12:25 pm INT RSSMC BG: 41.5 CPM^^
12:10 pm INT HEPA DUST from two HEPA filters, one Ionizer/HEPA filter from May 20 to today, or 43 days total: 134.7 CPM^^ which is 2.25 TIMES BACKGROUND HIGHER In just 61% of the time of the last period, the sample was 2.88 times higher over background than in the prior period.
May 20, 2015
4:45 pm INT HEPA DUST from two HEPA filters, one Ionizer/HEPA filter from March 11 to today, or 70 days total: 68.1 CPM^^ which is 78.8% ABOVE BACKGROUND which is just 20% of the radiation over background from the last period which was half as many days. This is a welcome reading and result.

9:00 pm INT RSSMC: 37.2 CPM^^
6:20 pm INT RAIN SAMPLE 3: 40.0 CPM^^
5:30 pm INT RAIN SAMPLE 2: 45.4 CPM^^ which is 13.8% above background but within the Inspector Alert nuclear radiation monitor’s conservative +/-15% margin of error meaning the reading is BG. [Note that in all three rain samples, radon progeny/daughters do not impact the reading as there is none in this area.]
5:15 pm INT RAIN SAMPLE 1: 39.1 CPM^^
5:00 pm INT RSSMC: 39.9 CPM^^
