An ionization type of detector forms anelectrical path inside a small chamber with a very small amount of radioactivematerial. When smoke enters the chamber, the particles attach themselves to theions and change the electrical current flow. A photoelectric type ofdetector works by using a photoelectric cell and a light source. The light doesnot usually reach the photoelectric cell, but when smoke is present the light isdispersed and reaches the photoelectric cell, triggering the alarm. The maindifference between the two types is photoelectric types are more sensitive tolarge particles and ionization types are more sensitive to small particles. Modern home design should include at least one of each type.

The Ministry for Home Security was headed up by Sir John Anderson the Home Secretary and Minister of Home Security. The Ministry's responsibilities covered all central and regional civil defence organisations such as air raid wardens, rescue squads, fire services, and the Women’s Voluntary Service. It was also responsible for giving approval to local ARP schemes, and providing public shelters. Home Security Inspections: What to ExpectHome security inspections are generally quick and inexpensive, but the results of such inspections are likely to improve your property for years to come. A good home security inspection will look at your property as a whole and identify any problematic areas where your home is either unprotected or under protected. Your windows and doors will, of course, fall under some of the heaviest scrutiny, as these are highly visible entryways for would be burglars, but these aren't the only areas that will be focused on.

We hope funds for this study will be forthcoming. Some of these points are also made in a reply to Bates and Miller: DL Bledsoe, BF Heald, LA Farrell, AJ Tucker, "Early Spaying Reduces Mammary Cancer Risk," Dog World, March 1993, 4 5. Some puppy bitches are born with immature or underdeveloped vulvas. These bitches, if spayed before their first heat, may continue to have problems throughout their lives. The physical results of going through heat often correct this problem since the vulva will swell during heat and not shrink back to it's former size though it does shrink down from maximal heat induced size. And one wants to prevent constant vaginal infections as they can lead to bladder infections and possibly kidney infections. Not all puppy bitches are born with this problem. For these normal puppies, spaying before the first heat does not pose any problems. The often cited problem of older spayed bitches having continence problems is not a function of when they were spayed. Many, but not all, will respond to estrogen supplementation. Of course, neutering will also help with the terrible dog overpopulation problem.
